I have no problem with tat's, I have 1 on my upper left chest, about the size of your palm. Planning a small addition to it soon. I do agree that tat's are something to get to sig something, whether it be an event, and expression, but i think it should be personal to you.
The wrist in my opinion isnt a very good place for one. Now, I do think it would look excellent there, but theres alot of things to consider, like how it would effect future workplaces, (granted that by the time im out in the "real world" for good, and employed, you'll most likely have alot more exec's with tats, its just becoming a more acceptable thing. But take in to consideration exposure to the elements, a tat getting in the sunlight will fade rather quickly, and will need to have work done on it much much more often than one that is normally covered by a shirt. not only would that get lame fast, it wouldnt look nearly as good, and could get expensive.
