Jonathan, I think there’s a lot to be said for the value of age and the quality — at least potentially — maturity can bring to our writing. We’ve have more experiences. We’ve seen more people. We’ve learned more. All of those things we can bring to the writing.
I sold my first screenplay when I was 34. Ava DuVernay (director, Selma) didn’t pick up a camera until she was 30. Sometimes life gets in the way of creative opportunities. Sometimes people don’t realize they want to write until they are older.
Whatever. If writing is part of their bliss, if it brings them joy and meaning, if their life would be less if they did NOT write, then really there is no option. Whether avocation or vocation, they have to write, if they want to have any chance of living an authentic life.
There are different ways to define success. Moreover isn’t more valuable to think about one’s PURPOSE, to seek THAT? Then if you hit the big time or not, you at least know you doing what you are SUPPOSED to do.
Good luck, Jonathan. Onward!
