I'm definitely not going to advocate that someone not try to better themselves. If you feel like you want to try to overcome some part of your personality that you're not comfortable with then that's a positive thing. I do, however, think that after multiple failed attempts at overcoming that trait, it's best to reevaluate your perspective on it. Sometimes it's best to admit that something is just a part of who you are and that it is, in fact, a flaw. Of course, we are all flawed in some ways, but it's how we learn to live with those admissions that will determine your self-esteem. Sometimes, even, what we think are flaws from one point of view are actually advantages when viewed from another. For example, procrastination is generally seen as a flaw or a "bad thing", but if you learn to take advantage of that by fully thinking out the problem you're actually trying to solve when you finally DO start working, you might might find that you create brilliant, innovative solutions to difficult things. Solutions that the non-procrastinator didn't think of because he was too fast to the keyboard.
I appreciate your reply. I think one of the reasons I feel that it isn't an innate trait for me at least is that I didn't procrastinate as much as I do now until I started college. Perhaps I always had this tendency, but its intensity is something I hope to temper. It isn't until recent months that I've decided to do something about it, so hopefully, I'm not due for surrender yet.
I had a rather romantic and gifted English teacher in my first year of college who claimed that procrastination is a part of the creative process, likening it hatching an egg, she claimed that procrastinating helped mature ideas before you put pen to paper, similar to the idea to use procrastination time to fully develop a solution to a problem, as you said. Yes, there is a correlation of my hearing of her doctrine and my increased procrastination, but I can't blame her for it.
