One of the things I have learned here and elsewhere. We are our own worse critic.
Take a deep breathe. Relax. and lets go sew something.
Life is a journey. So is sewing. As is anything we attempt.
My mom said a seamstress gave her a secret to sewing many years ago. " Pressing. Not ironing. The seams will make them lay flatter so they sew up better." It will make the points show up and line up so much easier.
So will having a consistent seam.
