Re: Mentor

@Kaylainfinity what skill level is your sim at? For fitness, mentor becomes available at level 10 fitness / or I believe if you're in the bodybuilder branch of the athletic career, you can do it earlier as it's part of the career.

For musical instruments, I think you need to be level 10 - when you reach level 10 in the instrument, the notification that pops up tells you that you can now mentor other sims.

The mentor reward trait you buy doesn't change these requirements.
