How do I take better selfies?

When I take selfies it all comes out bad.

I catch myself liking to capture an angle where my chest and above is showing and I’m showing the left side of my face more than my right, my face expression is a lil smile or looking away wtv pose I feel like doing, when I take the photo it looks bad. Like what I saw when I was taking the photo did not come out good as I thought. I do multiple attempts redoing it and trying different angles, poses, different lighting, switching the shirt, and it doesn’t come out how I wished it did.

What are some tips to take better selfies?
