BR/ Game selection game plan...I think I need some structure

[ssnyc]

Morning all...I need some direction. I've been playing quite a bit lately with some decent success and built my current roll from $350 to $3900 with some MTT and 180 wins (in the $5 to $20 range)...My problem is that I have no real game plan on what games/stakes/fields I should be playing.

I have been kind of randomly choosing SNGs (18, 27, 180 even 9pp) and doing most of the evening $5-$15 (occasional $25) buy in tournies.

Do you guys/ gals who take this seriously have a system or a plan for what you play in terms of buy in and field size? I would like to work toward improving but feel pretty random now and not sure if I should have a more structured approach...The good news is I've just about phased out short handed cash games (roll would be even hight without them!!!). I do well in live cash games but online I have a bad record so I'm abstaining.

Thoughts?
