The truth is that long lasting careers are built by people with life experience. It shows in the writing and creates more nuance, texture, grit.
I wrote my first book when I was twenty. Someone told me to forget it. No one buys a book from anyone until they are 40. Ha- well, there are always people who will be eager to tell you you can't do something. What they mean is they believe they can't do something.
I digress. My point being that writers grow into their craft-even after they publish. So keep writing. Keep growing. Have a great weekend. Cheers~
