I put my Simself on the gallery: #Simself - Seems like a good way to find other simmers simselves.
My traits: bookworm, computer whiz, loner, good, coffee lover(if there was such a trait in the game - I found a mod to add it), animal lover (loves cats and dogs), creative, gloomy, geek, lazy and erratic (but less erratic than in the game - I mostly talk to myself when I want to remember things or if I'm upset about something, and I only talk to objects that are malfunctioning - see upset about something). Also night owl.
So I usually create Sims with some combination of those traits since I can only pick 3.
