Article: It'll be easier for you to stay focused and motivated if you start your tasks with a clear head, so take 10 to 20 minutes at the beginning of each day to write a to-do list, review your calendar, and respond to a few emails. Giving yourself a little mental breathing space before jumping into things will help make you a better worker. Make it a goal to get to the office 10 to 20 minutes early each day for one week and see how it changes your attitude throughout the day. You'll feel better about your work and about yourself if you commit to doing the best job you can do in any situation. Instead of trying to rush through a task or project simply to get it done, ask yourself, “Is this something I can be proud of?" Proofread your work, do tasks that you notice need to be done, even if they aren't technically your responsibility, answer questions that might come up down the road, and think outside of your job description. Think about ways you can make your work even more dynamic, and try to implement those ideas when you can.  For example, if your job is to write a report about sales from the previous month, you could also include information about holidays, employees calling off work, power outages, and other factors that may have affected the results. Taking initiative and being responsible doesn't mean you have all the answers. If you're unsure of how to do something, don't be afraid to ask questions. Sometimes people do need a little reinforcement to help them stay on track, and that's perfectly fine. If you need this, arrange with a supervisor or a coworker to check in at a specific time every week for a “mini-deadline” to help you get your work done in time. For example, if you're working on a big presentation that is due in a month, arrange to send your supervisor a copy of what you've worked on every Friday at noon. That way, you know you have several deadlines to work toward and need to show something new every week rather than procrastinating until the last day to get things done.
Question: What is a summary of what this article is about?
Take time to prepare for your day rather than winging it. Focus on the quality of your work, even if no one will ever see it. Take the initiative to go above and beyond the minimum expectations. Set up accountability if you need help doing your best work.
Article: Atomic mass, the mass of a given atom or molecule, can be expressed in standard SI mass units - grams, kilograms, etc. However, because atomic masses, when expressed in these terms, are incredibly small, atomic mass is often expressed in unified atomic mass units (usually shortened to "u" or "amu") or in Dalton's (Da). The standard for one atomic mass unit is equal to 1/12th of the mass of a standard carbon-12 isotope. Atomic mass units tell the mass of one mole of a given element or molecule in grams. This is a very useful property when it comes to practical calculations, as it allows easy conversion between the mass and moles of a given quantity of atoms or molecules of the same type. Most standard periodic tables list the relative atomic masses (atomic weights) of each element. This is almost always written as a number at the bottom of the element's square on the table, under its one or two letter chemical symbol. This number is usually expressed as a decimal rather than as a whole number.   Note that the relative atomic masses listed on the periodic table are average values for the associated element. Chemical elements have different isotopes - chemical forms that differ in mass because of the addition or subtraction of one or more neutrons to the atom's nucleus. Thus, the relative atomic mass listed on the periodic table is suitable as an average value for atoms of a certain element, but not as the mass of a single atom of that element. Relative atomic masses, as listed on the periodic table, are used to calculate molar masses for atoms and molecules. Atomic masses, when expressed in amu, as on the periodic table, are technically unitless. However, by simply multiplying an atomic mass by 1 g/mol, a workable quantity is obtained for an element's molar mass - the mass (in grams) of one mole of an element's atoms. For example, the atomic mass of iron is 55.847 amu, which means one mole of iron atoms would weigh 55.847 grams. As has been noted, the relative atomic masses listed for each element on the periodic table are average values of all of an atom's isotopes. This average value is valuable for many practical calculations - like, for instance, calculating the molar mass of a molecule comprised of several atoms. However, when dealing with individual atoms, this number is sometimes insufficient.   Because it's an average of several different types of isotopes, the value on the periodic table isn't the exact value for any single atom's atomic mass. The atomic masses for individual atoms must be calculated by taking into account the exact number of protons and neutrons in a single atom.

Understand how atomic mass is represented. Locate atomic mass on the periodic table. Understand that periodic table values are an average atomic mass for an element.
Article: One of the most widespread symptoms of depression is sleep disturbance – getting either too much or too little sleep. Sleep is an important part of staying mentally healthy and when you don’t get the right amount, mood swings and depression are often the result. To avoid these negative consequences, prepare a sleep schedule. Coming up with a sleep schedule depends on your personal needs – some people need to sleep more than others. However, when depression during pregnancy is concerned, the generally accepted rule is that you should sleep about 9 hours per night, and have two short naps during the day (approximately an hour long for each). To reap the benefits of your sleep schedule, you're going to need to go to sleep and wake up every night and morning at the same time. It's best to have it at the same time every night so your body can get used to the schedule and eventually find it easier to sleep. This will mean some sacrifices, yes. If you choose 10 PM as the time to go to sleep, this includes weekends, too. There will be the occasional night when you want to stay up (or morning when you want to sleep in), but the schedule still needs adhering to. This might be difficult to do at first, and it is very likely that the first few times you will toss and turn without being able to fall asleep, but in a few days your body will get used to the new regime and things will get easier. Depression itself usually also affects your sleep. The biggest problem with this symptom is that it feeds a vicious cycle. In order to get yourself out of this sleeping trap and feel happier, you need to dedicate yourself to this idea of a sleep schedule and stick to it. Normalcy and routine are key. Sleep is especially important when suffering from depression during pregnancy because it is what allows your brain to fully rest and recharge. As your brain is the organ that controls your emotions, and therefore depression, depriving it from the right amount of sleep can be very harmful. If you spend a night tossing and turning, make up for it with a nap during the day. Two one-hour naps are appropriate during pregnancy if you did not receive enough sleep the night before. However, be sure that these naps don't interfere with you falling asleep and waking up on time the next day!
Question: What is a summary of what this article is about?
Take charge of the way you sleep by creating a sleep schedule. Go to sleep and wake up at the same time each day and night. Observe your sleep schedule strictly. If you get off your schedule, take a nap.
