Feeling unaccomplished and behind in life

I’m 25 and feeling very behind in life. I look at the ppl around me and they’re all doing so much better than I am. They’re accomplished writers, directors, getting promotions, starting businesses, etc. Meanwhile I feel stuck and as though I have nothing under my belt. I work an okay job but besides that there’s nothing more I can really say about myself and it’s really depressing. Idk what to do.
