I recently realized that I am one of those people who tend to over-think nearly everything. Which does nothing but turn smaller issues in to larger ones. After evaluating myself however, I have figured out how I can change this about myself. Yes, it is a juvenile answer, but it's true. Although it is definitely easier said than done. The process is rather simple, in order to not over-think you must:
1. Not take everything too seriously.
2. Not go off on a limb (i.e. turn a situation in to something completely different by making assumptions and guesses that more likely than not aren't true.)
3. Not isolate yourself to the point where all you think about is that one thought in your mind.
Just by simply following these guidelines I have already improved myself on the way I think about things. I would also like to point out that I am not changing myself for any reason other than me wanting to improve my own life. Will power can get you far, the problem, however, is that not many people have enough will power to try.
