This only works on Bob Newbie, they tutorial guy. When you start the tutorial (before betty). Do the money cheat so you have unlimited money. Buy a bookcase, piano, chess set, mirror and exercise machine. when the blue boxes appear telling you hat to do wait until it is in the corner, then tell Bob to study cooking, if it works he will be studying cooking without his moods going down. When he had 10 cooking points, study mechanical. Keep doing that and leave the body skill till last because his energy DOES go down. When you go onto the body skills make sure you have a coffee maker, when Bob gets off the machine with a bed above his head make him drink coffee, make sure his bladder levels don't get too low. Keep repeating and soon his skills will all be filled.
