Getting to two stars was the hardest for me. Once my sim hit that it wasn't so hard because of many things that seem to come together .. more interactions, opportunities, and perks that lead to better fame boosts. It just seems that once you arrive it's easier. From 3 star up .. even easier.
I personally wouldn't want them to make it easier than it is. The struggle in the beginning and work was fun to me.
I guess if I get tired of doing this part one day or want to set up some quicky celebs I'll just use the cheat.
