advice you wished you knew

[ImCrazy]

I am very new to hold em, I have played for a year now but only play money online and about 300 b&m hours with real money. My question to you more advanced players is what is something that you know now that you wished someone had told you when you began this crazy journey. I believe I am on the right track, I have read alot of books and stay disciplined when playing but I believe value can be added by learning from others mistakes, so please share and maybe you can help one of us "nubes" out...tyvm
