When is the last time you wrote something down? No, actually wrote it by hand, not type it into your phone, tablet or computer.
The act of actually hand writing something has a powerful effect on the brain. One study examined students who took notes on their laptop in class and then others who took notes down by hand, pen and paper. The students who took notes with a laptop took twice as many notes as the ones who wrote them by hand. But, when grades of the test came back, the ones who took notes by hand scored better than the ones who typed their notes. Why is this? The reason is because writing something down by hand forces you to engage in the activity and you retain the information differently than when you are pressing keys on a keyboard. In essence, you are performing a kind of study session when things are hand written. This could be for anything, not just school. If you are trying to remember something, if you hand write it somewhere, the chances you will remember to do it, is much better than if you type it somewhere.
So, how is writing something down going to relieve stress? Here is something I started doing 15 years ago and took me from an unorganized, forgetful person, to one of the most organized I know...
Each evening, I take out a piece of paper and a pen and write down my "plan" for the next day. I didn't have to go into detail, I simply wrote down things I was going to do/accomplish the next day. I would also jot down anything else that was on my mind so that I would not forget them. The act of writing these down in the evening not only prepares you for the next day, as all you have to do is wake up and look at the piece of paper and follow what you have written down, but it also takes anything that is in your mind that may keep you awake thinking about and transfers it to a piece the piece of paper. You have organized/prioritized your next day and you have taken anything you may be thinking/worrying about and put on the paper.
As I mentioned I started this process 15 years ago and because I was persistent in doing this, I used notebooks ($2 college lined notebooks). I now have over 15 notebooks that serve as diaries of my life. It's pretty cool to have your life/days documented and organize you at the same time. Try it tonight, write down what you are going to do/accomplish tomorrow and on the bottom of the page write down "write tomorrow list" so that you begin to create a habit that will organize/prioritize/relieve stress/document your life.
