Weather changes always affect the mood I'm in and spill over into my motivation and desire to do school work. I absolutely hate hot weather so I really have to force myself into a mood to do the assignments. Cold or snowy weather (not that we get much of that here in Texas) puts me in the mood to get down to work. Rain I have problems with. I used to love the rain. A few years ago there was a flood where I lived and I lost everything. Since then it really aggravates my depression and I can forget about the work till it stops.
