"You can't write." Yes, I can I'm writing now Whether it's good or not, I don't care. If you like it, do it, chase it, achieve it, don't let anyone take your happiness from you. If it makes you happy, that's all that matters. You don't have to be discouraged you can do whatever you want to.
Getting told you can't do something, or you're bad at it, it can be crushing. there's always going to be someone that doesn't find you to be their cup of tea and that's alright, you don't have to be. Besides, not everyone likes tea. You're not going to be perfect, that doesn't exist. It's a dream that we will never reach. Stop chasing something that is just a myth. You're you, that's okay
