LHE - How many starting hands do you play?

[Thirdman]

Hi,

I only seem to be playing 10% or less of my starting hands. I play my starting hands according to the text books but I don't think I'm getting enough action to maximize my winnings, trouble is when I loosen up I lose money. Should I be playing more hands on average or is 10% OK? What percentage of hands should a good player be playing?
