step one : decide what you want, what is your target performance level!
step two : disconstruct the skill,separate into smaller skills, practice the most important ones first!
step three: reserch the skill just enough to do the disconstruction to choose the most important sub skills, but not so much that become barrier to practice!
step four : eliminate barries to practice, make easy to do what you want to do!
last : practice what you want for a list 20 hours!
