Problems Painting.?

This is from my daily drawing book I get some paint on them, lots of days its just doodles.

But these are my students paintings, which I have a "HEAVY" hand in. If I can come up with ideas, draw them and chose the paint and brushes, why am I not painting for myself.??
I have a theory. I think my creative juices get used up. Or Im just lazy... which is probably the right answer. Hope this wave turns out for the kid. : ) Hang 10 Dude.
