Can anyone please translate these two different items?

İnsan sıkı tutmalı yüreğini ; çünkü gitmesine izin verirse, çok geçmeden aklı da gider peşinden !

Kaybetmeyi ahlaksız bir kazanca tercih et. İlkinin acısı bir an, ötekinin vicdan azabı bir ömür boyu sürer...

I tried doing it myself but, honestly, I don´t think I´m doing it right

My try as learner:

İnsan sıkı tutmalı yüreğini ; çünkü gitmesine izin verirse, çok geçmeden aklı da gider peşinden !

Literal: Human have to hold his heart tight; because if he/she allows it to go, soon his/her mind will follow it too.

Bit changed, hope it sounds better : Man should hold his heart tight. Because, if he lets it go (releases it), his mind will soon follow.

Kaybetmeyi ahlaksız bir kazanca tercih et. İlkinin acısı bir an, ötekinin vicdan azabı bir ömür boyu sürer...

Literal: Prefer losing to an immoral gain. Pain of the first one is a moment, the second one´s stings of remorse last for the lifetime.

Bit changed:It is better to lose than to gain in an immoral way. In the former case, pain lasts only for a moment, but in the latter, stings of remorse last for a lifetime...

İnsan sıkı tutmalı yüreğini ; çünkü gitmesine izin verirse, çok geçmeden aklı da gider peşinden !

one should hold his her heart tightly, because if one allows it to leave ,before long ones mind would follow 

 İlkinin acısı bir an, ötekinin vicdan azabı bir ömür boyu sürer.

one moment of initial pain the  alternative is the  pangs of conscience lasting a life time

my try at that bit

Good try, deli, besides you don´t learn without having a go. But: Go with Tomac for the second one.

How long have you been working on your Turkish, tomac?

Your translation was remarkable...

sana katılıyorum

Wow! Thank you guys! I tried translating it by myself but I was having a hard time understanding the phrases. I´m just beginning to learn so, unfortunately, my Turkish is that of a 5 year old.....

Scratch that, a 5 year old is probably better than me  

 Great translation but you have one little mistake. But it seems you corrected it in the second version of your translation. Here is it:

Literal: Prefer losing to an immoral gain. Pain of the first one is (wrong) a moment, the second one´s stings of remorse last for the lifetime.

The verb "last" is the common verb of two sentences and you should use "last" instead of "is" Your second version is correct

Hi Tomac, excellent work  and almost perfect English

I am envious of your language skills!!!

Just some small corrections to help with your English:

"Because, if he lets it go (releases it), soon his mind will follow it. (his mind will soon follow)

(I let/release, you let/release, he/she/it lets/releases, we let/release, they let/release) 

It is better to lose than to gain in an immoral way. In the former case, pain lasts for only a moment, but in the latter, stings of remorse last for a lifetime ...

Also, thanks for the colour coding with your translations. 

Thank you, friends, for your explanations and corrections, I really appreciate your help.

Thank you very much. It´s about 2,5 years now, but, honestly, without putting much effort, just studying and trying to translate/listen from time to time.
