Sims 3 possibilities

This morning I had half a mind to create a Sims family based on my own after reading this post on The Sims 3 forum. In the past I've always given my "me" Sim a Painting-related Lifetime Wish, even though I'm not the most Artistic person in real life. The Artistic trait has always been a standard trait for every single Sim I've created. Early on, my Sim's Lifetime Wish was to be a Celebrated 5-Star Chef. So do I make my Sim a martial artist, artist, nectar-maker or photographer?
