Ok, right there. If you really want a tattoo, then go get one. It doesn't have to mean anything. It could be something that looks bad ass and you just want to get it tattooed on you. I thought my first tattoo had to mean something too. You'll find that the experience of a fresh tattoo with a good artist can trump any personal symbology. What tattoos have you been admiring? Do those "mean something" to the wearer?
On the flip side, a candle burning at both ends, or a candle burning by itself, is pretty good imagery for losing time if you ask me. Google search reveals some good ideas, but no artists, so I'm hesitant to post a lot of pictures here.
Here is one from Grez in NYC. You get the idea. Added snake and dagger for badassitutude.
