Hi, friends!!
I come across some problems with a sentence in . I wish you can help me get through it. Thank you very much.

Quisque ipse se diligit non ut aliam mercedem a se ipse petat sed quod per se quisque sibi carus est.

Where did you come across problems? If it seems very difficult, how would you parse the different words?

It might help to break it up into chunks:
Quisque ipse se diligit
non ut aliam mercedem a se ipse petat [hint: purpose clause]
sed quod per se quisque sibi carus est. [hint: here “quod” = “because”]
