Thank you very much for your elaborate answer! It is very helpful. I am sorry that you got an impression that I want to swallow a pill that would make me know everything. My question was ‘what is the most practical way of learning?’ There are different ways of learning things (school, internship, or practicing). I just wanted to know others opinion. Also, I do not see what is wrong in wanting to learn things faster. If someone has free time, ability and drive – why not? Everyone chooses their own comfortable pace.
