Here are a couple of my tips aka 2 cents worth:
Cats, contrary to their belief, do not actually help you sew better BUT they are good for destressing.
Buy a good stitch ripper. That, too, can be your friend. (I, personally, named mine after one long weekend.)
A backup machine or two (or more) can be your friend when your main machine dies, or won't work, unexpectedly.
I agree with create for yourself and if someone else happens to find it beautiful, or even art, that's just an added bonus.
