I know people who worked with celebrities. They needed to sign non disclosure agreements to never tell anyone they worked with them. It needed to be done in private. Being famous you cannot even go to a karate class or be in a waiting room. You need body guards everywhere.
In Brazil famous people have their family kidnapped and need security.
Do you want this life?
If you owned businesses would you like to be private or all over TV?
If you wrote music would you like to write the songs of mainstream singers or be the famous singer? the pay is roughly the same. Only the writers are unknown to the public. The celebrities are everywhere.
