I learned the hard way that pushing through a lack of motivation only perpetuates the problem.
Much like writers block, that mental struggle exists in all arts. It’s a mix of being overworked and being void of ideas you enjoy.
Although you may not view it as productive, I seriously recommend holding off for a few days until you stumble into an idea you enjoy. I shelved a recent project for nearly a week simply because I didn’t know where to take it until I woke up this morning with a brand new idea I was excited to implement.
I’d define the solution in two parts. Time and Ideas. Give yourself time to do other things, even if that’s just playing a game for a day or two. In this time, allow ideas to come to you naturally by thinking about what to do. Repeat process until you feel that genuine motivation to work again, sometimes even the break of the cycle can leave you motivated to start even if you have no new ideas.
Sorry my response is wordy, but I’m very passionate about burnout.
