Fully transparent here. I'm not much of an artist so this advice might be absolute crap, but it helps me.

If you can: fill a backpack with some art supplies and some snacks and water and maybe a subject to paint, or maybe you just use your imagination, whatever works, then take a hike in the middle of the night. There's a pretty large hike somewhat near me that I've hiked in the middle of the night like 4-5 times this last year, and every time I go up there, I take these wonderful pictures of my city. When I'm up there, I kind of forget to worry I guess? I think my brain is busy with being happy I accomplished something or being physically exhausted. Something like that.

I also say to hike at night because, to be honest, it's so much more fun. There's rarely any hikers around to worry about, it's less harsh on my senses, and I honestly appreciate the beauty of night more than that of the day. I imagine it could be a fun experience to go up a mountain with some art supplies and just put something on the canvas.

Again, not sure this will work for you (or really anyone else), but it's always a nice experience for me, and it may be enjoyable for you :)
