preparation

I think I'm going to play devil's advocate here, just because there isn't one yet. I think one of the biggest challenges to preparation is to know the difference between under-prepared, well prepared, and over-prepared, not to mention the "causing yourself undue stress" level of preparation. Before you can adequately prepare, you have to determine your goals and think about what is sufficient to attain them (which I guess you could call extra preparation, but I'm a basically lazy person by choice, and so I think of this as a time-saving shortcut). I know a lot of people who under-stress things, and a few dear souls who overstress and overachieve, and the common denominator is always a failure to determine what's really necessary. Basically, we work for three reasons: because we enjoy what we do, so that we are free to enjoy ourselves later, or to better ourselves, which basically increases the efficiency with which we can get things out of the way so we can enjoy ourselves.

Yeah, I quite agree with it. When we're prepared, we can do anything. We'll feel confident and will not miss the every great chance and we won't be regret.
