To go along with practicing and doing the art you usually do, you should explore other forms of art.
Even if you are not good at whatever medium it can help inspire you or help you get out of slump. Also it can help as an outlet because it won't matter how good or bad it is.
Post an idea you have for an art project.
I'm going to make a collage out of magazines. It will have a theme of life vs no-life( like a polluted wasteland)
1. Paint portrait in only 2 warm hues in high saturation, say, green-yellow and violet. Gouache, acryllic, oils, whatever
2. Paint something with BBQ sauce.
3. Paint in MS Paint, alternatively 1 layer, 100% opacity, FINAL DESTINATION
4. Draw [First thing you lay your eyes on in your room] elemental
5. Draw wooden human and next to it human wood
6. Draw environment and then flip it so as the observer looks at it from the back
