Practice Makes Perfect buffs too powerful

I am not a big Live Mode player, so recently I finally made a sim with the new Practice Makes Perfect trait. Took a several sims days to realized that the focused buff became a problem. My freelance artist sim need to be inspired to deliver his best works, but it kinda impossible to earn inspired buff since he had focused buff all the time. I ended cheat the game and replace Practice Makes Perfect trait from my sim.
I hope this trait get some adjustment. I can't see myself using this trait for any of my sims.
