Water-Color Painting

I seriously dislike painting because I like to have control and feel that when  I'm painting. Especially with water colors It's out of control and I'm struggling to keep it all in order. Were is that undo button when you need it.

I also feel like it took so much time to set up all the supplies and clean up when I was done. Also the amount of time I had to leave it to dry and come back. Not sure if it was worth all that effort - or I'm just lazy.
