In one sentence, describe what the following article is about: Part of what makes uncertainty so scary is that we feel that we don’t have any control over the situation. This will depend on the specific uncertainty that is bothering you, but if you can find something small that you can predict or plan, then do so. For example, if it is uncertain whether or not you will be moving to a new country, or whether you will be accepting a new job in your current country, make plans for how you will enjoy either outcome. If you end up staying, you might join a new gym, or find a new flat. If you move to a new country, look into the opportunities that expatriates have in that country to get together. If your uncertainty is related to a decision you have to make, then try to find ways to reduce the number of choices you have.  Use things such as your values, beliefs, and ultimate life goals to help you reduce the choices, if that is relevant for your decision. For example, if you are feeling uncertain about a few job offers you have received, think about how each job will help you accomplish your career goals, but also about how they will influence your quality of life. If you have a very involved family life, it may not be a good idea to choose a job that can call you away at any time of the day or night. This can help you eliminate one or two of your choices based on consideration of what is important to you. Setting goals can be a great way to help prevent uncertainties in our life, and when uncertainty does arise, have goals can keep us from getting distracted by this uncertainty. If you have something you want to achieve, then set a goal to do so.  For example, if you have a dream of attending a good college and becoming a doctor, then make that your goal. Whatever your goal is, write it down. This helps make it more concrete. Some goals may be more difficult to achieve, and may require more commitment, but with enough time and discipline, you can achieve almost anything. On the other hand, make sure you are realistic about your goal. Setting a goal to run a marathon in one month even though you’ve never run in your life is not a realistic goal. If you have a very large goal you want to achieve, it is best if you can break that big goal into smaller, more manageable “sub-goals”. For example, if your goal is to run a marathon, and you haven’t ever run before, make a few smaller goals that you are certain you can achieve. Your first goal could be to run one mile without stopping, then you could move up to running a 5k race. Once you’ve accomplished that, shoot for a 10k, and so on. No matter how much we might want to achieve a particular goal, there can be hindrances to achieving our goal. Therefore, it is important to remain flexible when it comes to achieving a goal.  For example, if you want to get into the best university in the country, but realize that you won’t be able to afford the costs of doing so, try looking into some other options. There are many, many good universities that are more affordable than some of the ivy leagues. On the other hand, if you simply must go to that expensive ivy league, consider attending part-time. This will give you enough time to also have a part-time job. Obviously this won’t cover everything, but it will help put some money in your pocket, and has the added bonus that you will have a bit of experience to put on your resume. In some cases, no matter how committed we are to reaching a goal, life or circumstances will get in the way. Therefore, it is always good to have a back up plan. This will also help to prevent uncertainty when thinking about your goal because you know how you will deal with an outcome that is not the one you are aiming for.  For example, if you have been training for your marathon, and you’re at the starting line on race day, but feel worried and uncertain that you won’t be able to finish, then let your backup plan be that when you get to the half marathon mark, you can stop if you feel that it is too much. Although this may be a slightly disappointing outcome, you can then take stock of your training, and have a better idea about what to expect next time. Then, you’ll definitely be able to finish.
Summary: Plan what you can plan. Decrease the number of choices you have. Set realistic goals. Take things one step at a time. Allow for flexibility. Have a back up plan.

After at least half an hour has gone by, take the screen out of the mixture, rinse it thoroughly under clean running water, and then wipe it clean with a paper towel. If you're cleaning the entire pipe, make sure to thoroughly rinse it with clean water and wipe it dry with a paper towel as well.

One-sentence summary -- Rinse and dry the screen.

Problem: Article: You should cut the stems at an angle while submerged in either a basin of water or running water. Exposing the cut end of your flower to open air can be damaging, especially since this is one of the points when flower tissue is most hungry for water. Additionally, you should try to cut your flowers in the early morning or late evening, as these are the best times to cut flowers. If you notice that your flowers, when cut, exude a milky liquid, you can prolong the life of these with a quick boil in water. Soak the bottom two inches of your cut stems in boiling water for ten seconds before putting into a vase. Two common flowers that can benefit from boiling are poinsettias and poppies. If your flowers have leaves all the way down the stem, these can rot in your water and cause mold to grow. Remove all leaves on your stems that will be below the waterline. You can determine whether your water is hard or not by noting mineral deposits on facets and kettles. These will often look like a white, scaly film when dry. If this is the case at your home, your plants will fare better with demineralized water, to which you can add vase preservative. Demineralized water is sold at most supermarkets and should be used in your vase solutions as well if you have hard water. Your homemade plant preservative will likely work even more effectively than commercial recipes, but these are an easy to use and inexpensive substitute if you lack the ingredients for the DIY recipe. Many times, a commercial preservative requires only a clean vase and warm water, though you should always follow the directions on the packet.
Summary:
Cut your flowers under water. Boil the stems of flowers with sap. Prune leaves below the water line. Use demineralized water if you have hard water. Add a commercial vase preservative to your water.
