I hope you didn't think I was talking to you when I called someone a 'fish', I was referring to another person who was trying to brag about their shorstacking skillz while betraying their lack of knowledge of the game.
You've shown that you want to improve, and that's one of the most important things in poker. You have lots of experience with SnG's, and you need to make sure that what you take from those applies to cash games. I do think you are on a good run, but there is absolutely no way you should be playing 100 NL even short stacked with a $24 (only 1 buyin

) or even a $150 roll. Shortstack play is just too swingy. Leave the money in the account unless you want to have to redeposit.
