One day during shooting I thought about how many consecutive free throws I could make. It ended in a bet (mainly with myself) that I could do 100 in a row by the end of the season. Working on that goal on and off for a few weeks, I realized that it is hard but still possible. I made 29 consecutive on day one and since then improved to 38. That does not seem like a big improvement, but the number of longer streaks increased a lot and it definitely helped improve my form and my overall shooting.
As I expected, it's more of a "mind game". The challenge seems to be to stay concentrated doing the repetitive task of shooting a free throw for at least fifteen minutes without losing focus. Every time my mind wanders for just a brief moment, chances are I miss the next shot.
My question is, how do pro athletes (from whatever sport) deal with problems like that? I watched the World Darts Championships recently. On that level many of the throws are easy (theoretically). The challenge is more to score consistently under pressure over the duration of a match. I guess the same is true in many other sports where precision is important. Once you mastered the technique, how do you fade out everything else and repeat that same move over and over again without losing focus and precision?
