I like Breandans suggestion of diúltaigh do cheann and the meaning but I know there was a question raised, I just want to make sure that the translation is correct...especially since this is for a tattoo. I want everyone to know that I am very thankful for all the help and look forward to further suggestions.

Oops, I forgot to reply to Tiarnan's post (and it was an important one.)

I think Tiarnan is right about ceann. We need to find a word that means "what the head thinks" as opposed to "what the heart feels." Meabhair might work, but here are some similar words for comparison:

meabhair "mind, memory, intellect, power of thought, attention, consciousness, awareness, reason, sensation, feeling, sense, meaning"
intinn "mind, mental state, disposition, bent of thought, attention, spirits, intention, accord"
aigne "nature, character, mind, disposition, spirit, cheerfulness, intention, stomach"
intleacht "intellect, intelligence, ingenuity"
smaoineamh "thought, reflection, idea"

Tiarnan's suggestion after imfhios/iomas was:

Bris na rialacha; seas leat féin;
diúltaigh do mheabhair, lean do chroí

Next to intleacht De Bhaldraithe has "(opposed to emotions)". So perhaps one of the following might also work:

Bris na rialacha; seas leat féin;
diúltaigh d'intleacht, lean do chroí

Bris na rialacha; seas leat féin;
diúltaigh do chuid smaointí, lean do chroí

(do chuid smaointí "your thoughts")

Perhaps the last version can be reworked into something like diúltaigh a smaoiníonn do cheann; lean a mothaíonn do chroí ‘refuse what your head thinks; follow what your heart feels’?

Always wait for at least three people to agree on a translation, especially if it’s for something permanent.

My translations are usually GU (Ulster Irish), unless CO (Standard Orthography) is requested.

Bris na rialacha; seas leat féin;
diúltaigh do chuid smaointí, lean do chroí

(do chuid smaointí "your thoughts")

I really like the meaning and flow of this translation by Breandan, would I be able to use this one for my tattoo? As always thanks for all the help that everyone has given me!!!

Its been awhile since anyone has answered this, so I just wanted to make sure that everything is translated correctly and that its safe for me to go ahead with my tattoo...thanks in advance for all the help!

I am planning on getting my tattoo in a couple weeks and want to make sure that everything is translated correctly, there are a few different translations for me to choose from and I would to know which one is the most accurate. Thanks for all the help with this!!!
