Article: Wash the jars and lids with hot, soapy water and place them in a pot of simmering or almost-boiling water. Putting them through a quick rinse dishwasher cycle immediately before use will also work.   Do not use storebought jars (such as mayonnaise jars). These have a high chance to break or fail to form a proper seal. You need a glass, threaded jar with self-sealing lid intended for home canning. You should clean the jars well, but you do not need to sterilize them. The pressure canner will accomplish that for you. (You should always sterilize jars before water bath canning, but that method will not remove the toxins that can thrive in canned beans.)  Keep the lids in their own pot until you need to use them. They should be packed closely, but not pressed too firmly in, since they require room to expand and contract during canning. Make sure your Mason jars are clean and their hermetic seals are intact before using. Leave about 1 inch (2.5 cm) of "head space" at the top of the jar. This will free any air bubbles trapped in your jars, which can weaken the seal and disrupt color and flavor. Use a clean cloth to wipe the rims of the jar. You don't want any contaminants inside your jar. Use tongs or a magnet to pull the flat lids out of the pot of boiling water and place them onto the jars. Screw the rim of each jar over the flat lid, protecting your hands with an oven mitt.

Clean and heat your Mason jars. Pack the prepared beans into the jars. Fill each jar most of the way with boiling water. Run a knife around the edge of each jar. Wipe the lids clean. Attach the lids to the jars.

Instead of one super long break, take a few short breaks in between different assignments. Maybe have a five minute break for a snack after 30-60 minutes of work.  Take five minutes to stretch, pop outside for a walk, or do something active, instead of just sitting and checking Facebook. It's important to make sure that you aren't sitting at a desk for hours and hours at a time. When you don't take breaks, the work can seem kind of endless. Productivity and concentration suffer, because you end up wasting some time doing other things like going on social media, doodling, or just doing poor work. Caffeine gives some students a much-needed jolt of concentration juice. For others, it's a fast-track to jittering around like a squirrel on speed. Don't drink more than the normal amount of coffee or caffeinated drink you usually consume. It will make concentrating harder. Better than caffeine is just staying hydrated. Drink water or juice instead to make sure your brain is functioning on all levels. It can be kind of hard to focus if you’re alone in a tiny room with just your books and papers. Sometimes it can be helpful to work out in the open where there are other people, or to study in a big group. They can be helpful in keeping you accountable. If you say that you’re working on an essay and they see you browsing Tumblr, they can point it out and keep you in check. As long as you're not sharing answers, working on homework together isn't cheating. Really, it's just smart time management and study skills. It's important to give yourself a reward for the hard work you're doing, each time you finish a task. Working toward a fun activity, treat, or some leisure time helps to motivate you to finish your work quickly, which means you'll have to concentrate.  Try this: Cut some colored paper into strips or squares and write all of your assignments you have for that day. Put these in one pile. Create another pile with an equal number of rewards. Put checking your phone or Facebook page on one, playing a game for 10 minutes, watching the new episode on TV, or anything that you want to do or would do in your free time. When you finish one task, pick a treat from the pile of rewards. This is a great way to get work done and enjoy the things you like to do. Don't get too carried away with the rewards. Only one episode TV, not the rest of the season.
