Profit or Fun?

By far the most profit I can consistently make is 4 tabling $3/6 for rakeback and bonus money. This is also the most stressful.

I find I'm having more fun with less stress playing SNGs or low buyin MTTs, and this what I've been mostly doing for the last few weeks. I still make money, just not nearly as much (but with very low variance compared to cash games).

Do you always play the games that maximize your income?

Or do you compromise income to play the games you find more fun and less stressful?
