even if life is a ***** you don't have to be one

Hi! Is there someone who's might be willing to translate it into spanish? Would really appreciate it! Greets hobert

there are quite a few variations.
Here's one possible version:

que la vida sea una m***** no significa que tú también tengas que serlo.

Is it also possible to say "aun cuando" instead of "que"? How would other variations sound like? Would really esteem other possibilities! :) Greets hobert

Another possible version:
Aunque la vida sea una mier** tú no tienes que serlo.
Hope you like it!
