Wow! Very cool, Paul! I think those with ink do feel that each one is significant to them. I know mine are. And I didn't even get my first one until I was 33. It wasn't on a whim at all.
its best to really think about it first, plan it out, have a few drawings done and only go with what you really want... ive waited up to a year just getting a drawing to where I liked it....no need to rush.
