When in doubt, give yourself a challenge-

 Paint something you wouldn't normally paint. Like a still life in the studio. Once in watercolor.

And once in acrylics. They don't have to be large. 5x7 inches for watercolors- 6 x 8 inches for canvas.
Then challenge yourself to make one hundred of them in one hundred working days. Or so.
Hmm.
