Being able to achieve a success metric is hard, but knowing which metric to achieve is even more important. Discover what you value and choose your own metrics for success, otherwise, your environment will dictate it for you, which could be unfulfilling for you.
Work towards your own idea of success and don’t let “FOMO” make you feel like a failure because you’re not meeting someone else’s metrics for success.
Don't know anything about OKRs? Read The Art of the OKR first, and/or Personal OKRs I teach at California College of the Arts and Stanford Continuing Education (you can take the Creative Founder class this January) I've spoken around the world, from Tel Aviv to Grand Rapids Michigan to Buenos Aires, and given workshops publicly and privately (you should hire me).
