I agree with PPs. I only have one tattoo so far, an arrow, and it was to cover up another tattoo. It has no special meaning to me, I just like the design. In a few days I'll be getting some wildflowers done on my leg because I think they're pretty and I think this artist will do a great job. Tattoos don't have to mean anything at all and they definitely don't need to mean what other people say they mean (unless perhaps it's a well-known symbol like the cross). I imagine that one day I'll connect something or another to my fairly meaningless tattoos, but for now they're just body art.
Not trying to say there's a problem learning about what op's tattoo means! I think knowledge about the design's history, use, and implications is extremely important and helpful.
