Tradução - Grego-Inglês - ζησε με το θελω τησ καρδιασ σου και οχι με το...

It's a paralel between your wish and the exigency of others. Live according to what your heart wants and not according to what the others want you to do, others' requirements, "must do".

I agree with Freya
Perhaps the parallel between what your hearts desires and what the others want you to do is already highlighted in the original text?

"Live according to the wishes of your heart, not according to what other people want/demand from you"

Would that convey the original?

I can't say anything about the Greek source, my opinion was based only on the Spanish translation and I guess Tzicu-Sem translated according to the Greek text, probably.

Same as Freya.

I think the translation should also have quotation marks around the two central words of the expression. I also think "quiero" is closer to "I want" "I need" "I love" than on the word desire... And´"deber" is closer to "ought to" or "must"...

"Live according to the wishes of your heart, not according to what other people want/demand from you" sounds good to me.

In Greek, the literal translation would be "Live with the I want of your heart and not with the you must/have to of the others."

I would say that we should keep that way to express the idea, and the quotation marks would clarify the meaning:

Live with the "I want" of your heart and not with the "you have to" of the others.

Hello,

I'm lost in these comments. I think it is about several target languages.
Yes, I translated it from Greek so maybe better to check with a Greek expert...
