it's hard for me to find some motivation, it always depends on my mood

I'm sorry but I think you asked the wrong person, haha. me also still figuring out how to motivate myself cause I somehow feel half-dead to some extent. this is obviously not the correct answer but this is just me sharing what I do most of the time: pretend. just pretend like you're motivated enough, pretend like you basically want to do this and that, pretend like you're excited, and stuffs. fake it till you make it people say, ain't it? if you can't be genuine to do something, just pretend.
