[quate]What do you do in this case? Do you really only play if you have something? That works well to keep you from losing all your money, but it also won't win you much, and it means nine times out of ten you will fold. [/quate]

yep - you only play of you have a hand.
It will win you nice money, if you really play tight.

Regarding the number of flops to see - that really depends on the number of players in the table. Seeing only 10% of the flops is a bit on the tight side. I think on average you should see about 1.5 hands per orbit.
