I just cannot for the life of me grasp lighting. Any advice?

I have been taking pictures for a few years. I’ve moved on to photographing people. I’ll take like 50 shots and I’ll be like WOW to a few of them and it’s just the lighting. This does NOT come naturally to me. The adjusting your subject in an outdoor shoot with the sun in different locations. The constant changing of manual settings. Im not sure why it just hasn’t “clicked” yet. What helped it “click” for you?
