What kind of tattoo should I get to convey this meaning?

I’m getting my 3rd tattoo and although it’s taken me 3 years to get more ink I want this to be my last. I have the idea of putting “set it free” with “pura vida” underneath on my foot. However I want something in between the 2 sets of words… the meaning behind the tattoo will be one of allowing myself to let go and live a full life without holding regrets and waiting around for things to come. However I’m not sure what symbol/flower/bird/etc conveys this feeling.. I’ve been trying to search for meaning behind certain pictures but I’m not getting much luck.

I need serious suggestions only, this is going to be with me forever.
