I wish you the very best of luck. Do it and don't look back.
I always tend to think I'm NOT a hustler, and then I remember how I stood behind a farm market table with my parents and sold sweet corn starting at the age of 10. And worked three jobs through most of college. And always freelanced even when I had fulltime work. So yeah, you can be a hustler for a long time...but it's hard to do it forever, even if you want to.
That's part of what pisses me off about Medium. The relentless push to make people publish every day, rather than just letting them write on their schedule. I get that it's their company and their platform, but still, I think driving people that hard is unsustainable.
