and yes, you started a thread asking for best poker advice? Sixfour made a snarky comment about you asking for advice...then you providing your own brand of best advice. 10/26 posts in this thread are yours. No law against it of course.
Follow proper bankroll management..... if you can't take swings, I'd say adjust and be even more conservative with your bankroll management.
Find a game and master it. Ex: if playing online, become a cash player, sng player, or mtt player. I would honestly say cash is best for overall bankroll fluctuations as variance is high in mtts. I feel becoming a master of sngs is best as it can really help your ft mtt game. I feel sngs are best to multitable and build a roll with as you learn a lot about end game for your mtt play.
Finally, learn to fold big hands. The difference between a good and great player can be letting go of a top hand when you know you are beat.
