I have been playing poker for over a year now, have built a bankroll of 2200$ playing SnGs and small MTTs and am occasionally reading some articles, watching some videos, attending coachings, posting hands every now and then. That is not enough for me though because I seek a faster development than an occasional article or video. I am, however, unaware of what and how to study to improve in the most effective way. Should I book private coachings, should I spend more time reading articles? The way I'm learning now is way too vague and I get a grasp only of general knowledge which is not what I want. But what to start with I have no idea either.
