How long would it take to learn trading?

I spoke to a tutor who teaches trading, and he said for his lectures, he teaches for an extended period of nine months for anyone who wants to learn trading from him. Please I like to read the personal experience of some traders here, how long did it take you to learn to trade profitably, and what was the hardest thing to learn? did it take you weeks, months or years? Do you think that trading can be learnt well in a short time like three weeks for a quick trader? Can someone who is a profesional trader just go straight to the point pointing out what is needed to make a successful trader to a newbie to learn quickly?
