Tattooes

A long time ago I heard a very good bit of advice surrounding when to get a tattoo.  The advice was to write down exactly what you want and where you want the tattoo and put it in a drawer for a year.  After the year is up you decide what tattoo you want and where you want it and check to see if your current desire matches up with what is in the drawer.  If they match and you haven't changed your mind in the interim, go ahead and get the tattoo!  Otherwise, write the new preference down and put that in the drawer for another year.

Seems like good advice... but the question remains as to whether this is a necessary or sufficient condition.  I have known for years that I want to get the ace of spades and a 20 sided die tattooed on me if I get a tattoo and I know that I would put them on my inner arms.  (Visible when in casual clothes, hidden in formal clothes)  Am I now obligated to get these tattoos now that I have completed the recommended preparations?  My parents were definitely against tattoos when I was younger although they clearly don't get much say in the matter these days!  My brother and my sister in law both have tattoos that I like and both chose tattoos that were particularly appropriate for them; though I generally don't think keeping up with the Joneses is especially useful it does tempt me.

Clearly I am not the first to come up with this theme, as the following pictures from the internet show admirably.

I don't especially want gigantic pictures on myself but rather just small graphics.  Is it go time?
