Even if the "eating" comment was a joke, I stand by my comment that you're better off finding a new hobby if you're shortstacking 25NL because you don't have the confidence to play it full-stacked.

If you just want to play a few hours a week for fun, then obviously, screw around at 25NL all you want. But if you actually want to make some money, you need to be playing 100NL at a minimum before this this game is really worth the time, otherwise you're better off getting a job. Playing lower stakes than that is only worthwhile insofar as it improves your bankroll and skill until you get there, which shortstacking really doesn't do so it's just a waste of time in my opinion.
