What do you think about me accepting another job after already accepting another one?
Why would you accept another job?
So that my friend won't be jealous of me doing another job with better conditions.
It's not cool to accept two jobs at once. You should only accept one or the other.
I'm doing it because my manager asked me to do more. I don't want to upset him and give me more work.
You should choose which job is more beneficial for you and stick with that one. It's wrong to accept to job offers at the same time because you will not be giving each job the best work that you can.
