Painting should be fun. Once it doesn't, stop painting and do something else. Set realistic goals. As in my case, perhaps 10 of them. It sucks really bad having something nagging on you when you're in the mood for painting something else.
Of course, if you really have to get stuff painted. Like if you're attending that tourney in 2 weeks and everything still is grey plastic. Paint. Paint like a madman and embrace the suck. If not, make sure it's fun to paint so you don't end up with too many "I really need to paint these but I don't want to". Hobby should be relaxing and not work.
Fire up some podcasts, make a cup of tea, relax, paint & smile. :)
