Probably know the answer but ... (help needed)

The answer is: (What is) take some time off and study.

The question is: Looking for advice on a next step. I'm stuck at $2/4. I'm not dominating,I'm only a slight winner (<1 BB/100), I play too loose (30 VPIP) and there are leaks in my game. But I play for fun/entertainment and I still really like to play. I'm getting stale and need a challenge/different level. My bankroll keeps fluctuating around 300BB for 3/6. I build it up and then go through a bad streak or tilt some off over the weekend and start all over again and build it up. But 3/6 seems like a rock garden. I get the impression that the general consensus is bypass 3/6 at Party. So where do I go from here? Is there another site where 3/6 is a step up from 2/4 but there is still a good game? Any constructive advice would be appreciated. I'm stuck at 2/4 and probably don't have all I need for the next level but would really like to learn as I go (play). Maybe someone who has been where I'm at can shed some light for me?

Thanks in advance for any who reply. Cheers!
