Nobody expects anywhere near the same level of perfection that you expect of yourself. Nobody looks at you the same way you look at you.
Nobody else notices your wrinkles, the way you speak (that you hate) or the way you wave your hands when you talk.
All people want from you is something that will help them. If you’re good at providing that you could look and sound anyway you like so long as the information you’re providing is easy to consume.
When we're creating something new we have to be careful not to become obsessed with it being good, because it won't be. Anything we start that's worth continuing will be average at best, terrible at worst.
Focus on the process of creating, and not what other people think. Forget perfect, because you'll never reach it. Make something because you have to.
