I have a habit of making myself worry about things that do not necessarily warrant any worrying. I find myself looking for things to ponder my head around. I know it sounds crazy, and I never knew I did that, until I was speaking with an important lady in my life today, and she made me come to terms with it.
For example, I find that I cannot just simply take what is in front of me. I do my research to make sure that I am very familiar with it. I guess being informed is a good thing in a way because I know enough information about everything I invest my time into. However, sometimes it is a bad thing because I let emotions get into my way of knowledge, and I second guess my potential. This flaw of mine has cost me a a lot of time, and I end up wasting time trying to find a good solution when the easy solution is to just accept it.
I am not sure if I am making any sense at all to you right now, but I guess my point is that accepting a difficult situation is always a lot better than trying to find reasons to why it happened or what you did wrong. But, acceptance is not always an easy thing. I have learned that it is important to limit your worrying, so you can stay on task, and do what needs to be done with a clear head. This is especially important in medical school. Just food for thought.
