Hello - I was looking for help translating a phrase for a tattoo. "Live and Let Live" Any help is greatly appreciate. Thanks!

Things which can be said succinctly like that in one language can't always be said so succinctly in another language., and i can't think of a short way to say that expression in Irish, without including direct and indirict objects of the verb "live". If you can tolerate something a bit longer, this would work:

Mair do shaol, 's lig do dhaoine eile a saolta a mhaireachtáil.
Live your life, and let other people live their lives.

There's a traditional proverb which expresses roughly the same sentiment:

Lig dom agus ligfidh mé duit.
Let me be and I will let you be.

or you might like this more colorful one, in the vein of "don't mess with other people", which is actually a tongue-twister in Irish:

Ná bac le mac an bhacaigh, agus ní bhacaidh mac an bhacaigh leat.
Don’t mess with the beggar’s son and the beggar’s son won’t mess with you.
