Enhance/improve my tatoo

[Cerat]

I have a tatoo which says "peace". It's a small chinese blot, which is to small, and actually meaningless. I need it to mean something, so I'm thinking to add another chines or several chinese-signs, making it meaningful. What chinese-signs can I combined with the sign "peace", leaving the tatoos to say something?

Is it possible to let it say "believe in your self"?
