I guess that depends on how much you love writing. I don’t think there’s an easy answer for that.
There have been times when I’ve given up on myself, but I’m so addicted to writing that I start to go bonkers if I go too long without doing it.
You just have to keep plugging away at it. And try to get feedback from other people from time to time. They can point out things you don’t see yourself.
It’s also an amazing feeling when one of those people point out something you used to be terrible at and say, “That thing that you did really worked.”
Whatever you do, don’t give up!
