I draw since I was a kid. I had very little formal training. I finished 3 semesters of an advertising school around 2010. It included live drawing classes but we received very little instructions. Still, it managed to improve my drawing a lot - mainly thanks to having a book titled Fundamentals of Drawing by Barrington Barber.
Between 2010 and 2014 I was wasting my time and money trying to get into IT/vaguely pursuing a my dream of becoming a game developer.
Due to much values orientated personality and not deriving pleasure from bending hardware/software to my will and general lack of interest in new technologies, I haven't got deep enough in into it to make it a viable career or at least allow me to make a game.
So, I'm back to taking drawing seriously.
