<p>I've had both my biggest wins and losses playing NL. I think long term I would probably make more money there, but since I started considering it my "job" outside of school, I'm just looking to avoid the variance. NL is a more interesting game, where your intermediate term variance is significantly greater.
And fwiw, I started playing online poker when I was 15 so you'd probably be ok if your parents were ok with it.</p>
