How low can you go? (vpip)

[JTrue14]

Hello.
I recently moved up to the 3//6 short handed to test out how the games are. A friend of mine told me the short handed were great for him at 5/10 and 10/20 on party.
Anyways, I just started and I know I don't have many hands played (1k hands), but I was wondering if im not playing enough hands/aggressive enough. My vpip usually hovers around 13-14 (my friend makes fun of me all the time [img]/images/graemlins/frown.gif[/img] )whether it'll be full or 6 handed.
