Regular Painting

I've recently been looking at blogs and websites of artists doing (or at least attempting) a painting a day. I think this would definitely be possible if I made my living through painting, but I don't. Instead, what I've decided to try to do is a painting a week.

I think my subject will be landscapes since i've done very little "plein air" painting. It's an area I could improve on. Here is some of my past artwork (sorry about the poor lighting quality):
