That one time when I started drawing again and told my friend I would one day draw as well as my favourite artist. To which, she looked me dead in the eye and said, her tone doubtful, "Are you sure? They're really good."
I quit drawing for months after that. But now I'm back to practising again because I've concluded that my skills don't depend on her expectations. I mean, I'd felt the same way about writing once, but I love drawing and writing too much, and paired with my competitive ass, it's hard to just give up. The only way I would would be because I'm lazy.
Thing is, the more demotivating something is to me, the more motivating it becomes later on. I'm an insecure little shit, sure, but I'm also very prideful. Yeah, I'll be wrecked for days, then at some point, I just get all riled up and ready to prove them wrong.
And if they don't care, well, there's always someone else to impress.
