"He who conquers, conquers himself"
As long as it has personal meaning then that's cool, cos if it didn't and someone asked you why you had it tattooed on you and you said: "I dunno, it sounds cool" you would look like a 100% total wanker.
I prefer tribal, hence why my entire left arm is covered mid upper arm, all the way down to my wrist covered all surfaces of my arm. And a huge one of the same style from my right knee down to my ankle.
But each to their own, you need to get what you like done, otherwise there is no point in getting a tattoo.
