Hello, I will not agree with you that poker cannot remain the main source of income, many people who play on a regular basis or professionals who earn poker, just I think it is not given to everyone, just do not need to overestimate their strength and skills! In order for poker to become the main source of income for you, you need to work a lot on the game, and of course you need a sound understanding of when and how much you lose and be able to stop on time, do work on mistakes! But I may not be right, but this is my opinion and I can express it! It's just that I think poker can be the main source of income, but for this you need to do a lot of things, and not just play! I wish everyone good luck and play responsibly!
