I love the philosophy of Bruce Lee and If you ever want to understand key skills, visit his work and words, for he understood the value of and the need to incessantly practice them.
The following are a few quotes from Bruce and explains key skills to a tee and he also had developed the succeeding mind so he could train the key skills.
The quotes being:
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
The less effort, the faster and more powerful you will be
Take things as they are. Punch when you have to punch, Kick when you have to kick
Art calls for complete mastery of techniques, developed by reflection within the soul
Preparation for tomorrow is hard work today
The successful warrior is the average man with laser like focus
These movements can be mastered with practice, more practice and still more practice
You can tell Bruce Lee understood simplicity, for it’s there in his words to see, for:
Simplicity practiced lots, brings the mastery out in all
