I want to remind myself to be happy! ;-)
In that case, I'd go with one of these:
Bí sásta = Be happy (satisfied)
Bíodh áthas ort = Be happy (joyful)
They both mean different things, so you have to decide what kind of hapiness you are talking about.
Wait for at least two more people to confirm my translations before you get a tattoo. Our rule here is that three people should agree so you'll know there are no mistakes.
I like
Bí sásta "be happy (with your lot/with what you've got)".

But it may depend on what nuance you are after.
Another suggestion that might capture the feel of "be happy" less literally is:
Bain ceol as an saol. "Get the most out of life", literally "Get music out of life."
Await further input ...
