I am the absolute worst at time management. I am super scatter-brained and I never know what I'm supposed to be doing. This is a problem that I am desperately trying to solve.
So like any good little millennial, I took to Pinterest. There is a huge consensus on the basics you need to have under your belt in order to have good time management.
Number one; organization. You want to organize yourself, your life, and your events. Try and keep your space as uncluttered as possible. Put your clothes away after you do them, have specific spaces for your school items and your personal items and make sure you put them in those spaces when you are not using them. Make sure you write down what you need to do and when, make to-do lists for the day.
Number two; prioritize. Keep a planner and write down what you need to do in order of importance. Do the pertinent things first. Stop pushing things away and saying that you will do them later. Do them when you get them!
Number three; minimize distractions. When you are doing your work turn your phone on 'Do Not Disturb' this way you won't get any small distractions. This is perfect for me because I always worry that I will miss a call from a family member, but since they're on my favorites list the call will come through.
Number four; don't bite off more than you can chew. It is completely okay to say no, or to change your mind about things. School comes first. You are paying a large sum of money to learn and succeed. If you put too much on your plate and find that your grades and/or emotional state are faltering then re-evaluate your responsibilities and figure out how or what you can eliminate in order to increase your success.
Number five; don't be a perfectionist. Chances are that the thing you are worrying about is insignificant. An artist is never satisfied with their work and yet to another person it's a masterpiece. I'm not saying, do the bare minimum, I'm saying do it but don't waste time fretting over it when you have done it to the best of your ability.
Number six; practice self-control. If you know you have a paper due in two days, don't go out and put it off. Start the paper. If you know you have a test soon, make sure you are making time to study for it. Again, your education is the most important factor right now. So, prioritize it.
Hopefully, this will be helpful. I know that from time to time I need a reality check. Keeping yourself in line isn't always easy but it is a great skill to master. Mastering it now will be such a major asset later on in life.
Sidenote: I write everything down. What I don't right down I tend to forget. Now, I just have to find a way to organize my random thoughts.
