Inspiration is a fickle beast

I've been finding more and more recently that I'm really picky and finicky with a lot of stuff I do. I do anything creative, be it lyrics, photography, any kind of writing whatsoever, but I'll come back to it later, and feel totally different. I can't count the amount of times I write some lyrics that I love at the time, I'll come back two weeks later, and it feels shallow, forced, and cringy, and I'll absolutely hate it. I know it's my own problem, but it always irritates me when people seem to be able to write amazing things with what seems like next to no effort whatsoever.
