My training in Brazilian Jiu-jitsu (BJJ) can be related to that as well. Like many BJJ practitioners, I enjoy learning some fancy movements and techniques online. It was, however, only by stepping on the mat that I truly understood how the techniques worked. Additionally, I was frightened to attend any BJJ tournaments and fight with other athletes. However, the magic is that whenever I came back from a tournament, regardless of the result, I was on another level, technically, physically, and mentally.
Thus, if you tell me that you have come up with an awesome idea, I would encourage you to do it! Make it happen or at least know it isn't that great. If you complain that you can hardly understand something, I urge you to do it rather than thinking about it all day long! Trust me, it works! It is the power of DOING!
