I have noticed that if a peeps is struggling with their career I spend a little extra time with them. I put them on their career and watch. If they don't suceed I put them right back on it. If they do suceed I watch to see their next action. If it's anything but working on the career I put them right back on it and praise them again.
I keep this up until they suceed a few times and it really seems to help working take hold.
Also, I don't interupt them while they are working. If they are in mid-cycle I let them finish before moving them to something else.
I think this helps them develope the skill/experiance to try again and finish a cycle.
As far as arguing and making a baby...I just keep trying until they make up. I don't know if it helps but something I do is make sure they are fed, feeling fresh, have food, are rested and have no emergencies going on then when they do decide to try I praise them or give them a treat.
Again, I may just be getting lucky but it seems to be working out!

Good luck!
