Here's one for you, but I mean no offense to the rest of the players out there.
95% OF POKER PLAYERS EITHER BREAK EVEN OR ARE COMPLETE LOSERS.
It's for the above reason that if you can learn to play in an "unorthodox" method which most people disagree with, hate you for or despise you as a disagrace to the game then you may find you actual succeed.
For example, with cash games... don't be afraid to look at ignoring nearly all the people on this forum (as the above statement suggests) and instead try things a bit unusual. Go for things most others will not.
Here's a few examples:
1.) How about looking at learning a short-stack strategy for cash games where you buy in for less than 50BBs?
2.) If you are going to play your SB, Always 3bet by 5x the raiser's bet and check-jam some flops with a short stack. Learn to recognise flops your opponent will have missed and where you block them from hitting with cards you hold then check-jam all in.
3.) If you are on the Button where the Cutoff or Hijack have raised and you want to play your hand... NEVER FLAT CALL. Always three-bet 4x their opening range, bet flop 1/3rd followed by turn of 60% pot sized bet.
A few unusual moves, but remember the general principle:
* To be a success, become an outlier as almost noone is successful at poker*
