Well let's not do too much off topic but I disagre with you. For me, something "that are beyond control" can not by anymeans be controled

I guess it's another point of view from this word that I admit can be interpreted in many different way.
Edit: To answer the topic, I think it's pretty hard. In my opinion, there is no classic scheme that need a lot more time to be an expert if you start from level 0.
