Probably.

I have about $300 dollars for poker.

I've done ok in the past at 1-2 NL Holdem tables, but I've never played with much consistency. I don't think I have ever gone broke, which means I probably wasn't trying hard enough.

I really want to play. I think I'm good enough to make poker like a second job.

I hear you want 200x the big blind. SO I would need $4000 for my bankroll. That seems so hard to get any other than playing poker.

We will see.
