What do you do to make your sim famous?

I use the Road to Fame mod, because I wanted my Sim to become a singer. Then I enabled both the GF star-system and the RTF one. I had him play and sing in front of audiences at the Orchid A Go Go, capturing the moment on his drone. I also had him sing at the karaoke bars and compete as often as possible. Before he was out of high school, he was a Global Superstar. RTF allows your Sim to record albums. I would have him model, too, so that photoshoots (again via RTF) would put him on the cover of magazines. I had him interact with his fans often, signing those autographs and taking Selfies with them. When he gained enough hit points (100/100) he started being invited to throw concerts. He did this a lot. I also had him keep up with his Simstagram, updating it all of the time, uploading pictures from his phone. (A Sim gets fame+ points for this.) Just keep working it and get that first star, Notable Newcomer. Then work like the dickens and fill that bar. Use the perks you get once your Sim achieves a star. Be strategic in the purchase of the perk. Take whatever path you wish your Sim to excel at and go for it. Best of luck!
