Practice. The girl in the picture brings to mind a lot of people who sport tattoos and green hair, except that she happens to be beautiful.
I think it is much more courageous to speak up for those who are ridiculed by others because they have a "difference of opinion."
Being unpopular for daring to disagree with the crowd in the name of altruism takes courage. Having green hair? Not so much.
That being said, if you are feeling the tatoo culture, that's fine. Just make sure it does not interfere with your getting gainful employment. Being poor gets old faster than you think.
Hey, am I a kill joy or what? But seriously, I wish you all the happiness and courage in the world. :)
