All perceived failures are simple examples of how not to do something. It’s simple: you will get the results you want, or the lesson you need.
Not everything in life turns out exactly as we imagine. Through your practice, you will be confronted with many areas of frustration, where you’ll feel like you just can’t “get it.” You just have to remember that in every attempt at “getting it,” there is a lesson helping you get closer to doing it correctly. Turn any negative feelings of frustration and aggravation of not being able to do something or not getting the results you want into a positive feeling of perseverance: skill gained through hard work over time. That’s the definition of Kung Fu!
