I have a translation that reads "Tada gan iarracht" but I want to confirm this translation before I get it tattoed on my body. Thank you so much for your help!

Yes, that's fine (but do wait for two more here to agree, just to be safe)

If you like, there are other things you can substitute for "tada" that mean the same thing:

Dada

Faic

Rud ar bith

There' may be more, but these are the ones that spring immediately to mind. No need to change "tada" if you're happy with how it looks, though...it's solid.

Redwolf

I read rud ar bith as "anything" as opposed to "nothing".

It can be either.
