I can't imagine not living a creative life, but it can also be a lifelong challenge. Pure joy and high energy one day, and, depending on how much you "put out there" exhausting the next. One of the great rewards from writing a daily painting or creative-based blog is that it really does help you focus and stay motivated.
Along those lines, the other day I came across this posting celebrating November as "Art Ever Day Month" (or AEDM)--inspired by National Novel Writing Month (aka Nanowrimo!) There's some great creative artwork by the participants so be sure to check it out or join yourself.
When it comes to creating art everyday, I'm reminded of what our novel writing teacher at Lighthouse Workshop coaches which is that essential "just do it" mantra. More specifically he encourages us to be OK with our SFD. Or "So-So" (fill in your own "S" word here as neeeded) First Draft.
For creating art, you need to free yourself in the same way. Details, minor adjustments, etc. should be left to the end.
I tell me students be OK with the "ugly stage"--embrace it! Why, because it means you are creating and learning. Quite frankly, I often learn more from an unsuccessful painting so I try to keep that in mind as well. Here's a quick "demo" I did for my watercolor students regarding negative painting, glazing, and line as a design element. A perfect painting? No. But did I enjoy the creative process, absolutely.
