I spent along time deciding what i wanted as they way i look at it you are limited space wise so use it wisely! I have 2 tattoos at the moment- one is on the base of my back and the other is on the underside of my wrist. Both can be covered up if needed.
I find that older people tend not to approve of the one on my wrist as they say 'what happens when your old- itl look stupid', so it might but it means something to me and id rather it look stupid than regret not having it done. I will have more but i must admit i do cover mine up for meetings at work as people (especially older) dont approve and it saves questions as to why i had it done etc... end of the day it does not and should not matter what others think as long as youre happy.

Hope this is of some help.
