You’re not alone in feeling uninspired at times. I don’t know of an artist who hasn’t gone through a funk. Honestly, I go through multiple per year, and sometimes they last for months. I find it horribly depressing, and it’s one of the bigger challenges in my life.
When I’m in a funk, I take a break and find things I like to do. Play video games, catch up on movies/TV shows. I also search around for new work to be inspired by. I eventually feel like I’m wasting time and the itch to create something grows into an uncontrollable urge.
In the end though, you need to find out what will get you out of your slump. In my opinion it is what separates artists from hobbyists. For example. I would LOVE to learn to play an instrument, but I’ve never been able to fight through the slumps, I will dedicate an hour a day for a month and then my interest will die and sometimes I’ll go a year or more before I pick it up again. If it’s something you want, then prove to yourself you can do it. This is an invisible wall that a lot of people can’t get past.
The one thing I really appreciated about art school was being forced to practice art for three years straight, even when I didn’t feel like it. I may have not creatively been there 100% but I still was improving my skills by doing things like life drawing, along with other assignments. If you are short of ideas, try to teach yourself something new. Use that time to build technical skills. If this is something you can’t push yourself to do, then it might be time to have a serious internal discussion about what it is you really want.
