It will cost you far far more than just the $100 estimate if you are not yet sure of what type of career you want for yourself in life or could qualify for.
If it messes up your chances for desirable jobs later in life, it will cost far more than you could imagine now.
Trying to get a tattoo lasered off the inside of your hand once you wake up to reality can be incredibly painful.
For your own sake, get it done on your shoulder or some other part of the body easily covered by clothing. This way you can have your cool design without screwing things up for yourself immeasurably.
You’re a very smart guy and could have your pick of any number of rewarding professional careers. Why eliminate your shot at many of them with something that visible. Please please use that brainpower to not limit your options in life so severely. No matter how cool you make the design, if it’s on your hand, there will be many future employers who will pass you by in favor of others with better judgement and taste.
That’s just the realities of life.
