When we tackle new challenge, such as the learning of new technics,most people may arise the mood of aversion and resistance ,irritated and overwhelmed by some unexpected problems. Some people think they have fizzled,and don't want to double-down focus all of their capacities in that again.Others may seem to be freak that still persist to pratice that.In my opinion, the letter people have insights on learning technics and tackling challenges, they may have more many chances to become facility in anything, in much the same way as challenge on how to tackle.
