When I first started playing sims I loved controlling every aspect but recently I've had to start letting go of the control with who they marry (MC Control Center) and now I'm randomising their traits and aspirations when they grow up for extra fun! I've recently had a girl who rolled randomly Lazy trait but aspiration of 'fitness'.....So she goes like half an hour sim time working out then whinges cause shes tired......but i discovered it doesn't happen so much with yoga. It's interesting to keep you learning things.
