Definitely man, don't think of VPIP as a target. Just stick with a strong hand range, add a few hands or drop a few hands as you gain experience, and the number will come out on it's own.
I played 20/12 when I first started playing 6max limit. I play more like 24/18 after a lot of experience, but some very successful players are much tighter, and some much looser.
