Which branch is more profitable for getting fame in politician career?

hello, one of my sim family was working for the secret agent but I realized it doesn't help getting fame from work. He was level 7 at secret agent but his fame kept dropping and raising between notable newcomer and rising star. He spent a lot of time to get fame without acting, recording movie or using drone stuff. I just wanted to test how to become famous without using Get Famous items. He purchased never weary trait, and he painted all through the night and played a lot of music and singing in community lot to become rising star. I don't know why he has seldom masterpieces in painting with creative trait. Of course he has completed painting aspiration long time ago. But looks like these are kind of limited. Other ones of my sims have done masterpieces values above 5000 simolens and they are global superstar, so they can sell their painting around 8,000 to 10,000 simoleons per 1 masterpiece painting include fame without creative trait.

So I think it could be better choose the politician career for getting fame but which one could be more profitable? It's a bit annoying that he still has to get donation from other sims at level 10, charity organizer. There's no daily tasks for level 10 in politician branch.
