Before you do something permanent, I would start by printing your design on temporary tattoo paper (for both inkjet [http://www.texascraft.com/hps/product.php?productid=16182&cat=286&page=1] and laser [http://www.texascraft.com/hps/product.php?productid=16546&cat=304&page=1]), and seeing how well you like it. You get 5 full letter-sized sheets for less than $15, so you can try lots of different versions of your tat.
Once you have decided on what you want, you only have three questions remaining:
1. Is it something (in a normally visible location) that a job interviewer/mother/etc. can see and appreciate?
2. Will it still have meaning to me 50 years from now? (or even 5...)
3. Is it something that will still be admired 50 years from now?
