I've been involved in donk level poker for around 4 years, and I've been through numerous thought processes and mini-epiphanies. After speaking to lots of different people and reading/watching lots of different stuff, I have to say that if you want a long term future in the game and any variant of the game, Spoonitnow is one of the only people worth listening to in terms of his approach i.e. math and theory.

Feel based poker (as opposed to math/theory based poker) is short-term imo.

Most players play the former approach, and that includes people who've made fuck tons from the game.
