"I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times." – Bruce Lee
Athletes must be focused in their efforts if they want to become great at their sport. You can't become great at tennis if you spend too much of your time practicing billiards, basketball, golf and soccer. The same holds true in life. If there's something you want to be really great at, you need to focus your efforts on it and limit your distractions.
