Is everything set in stone and you cannot change your fate?
I heard someone say something interesting this week:
"Some people are creative, others aren’t. There is not much you can do about it."
Honestly, I don't agree with that. In my opinion creativity can be trained, just like playing an instrument or getting better at certain sports. Writing is hard work and some days are better than others. If you really want to write, just do it and don't give up just because someone says, you're not good enough.
Even if these people are right and you aren't good enough the first time. If you keep trying, you will improve.
