Please do not have the mental mysophobia and perfectionism

As an engineer, the stereotype is rationality, and mathematics and engineering are not subjects that encourage people to make mistakes.Engineering ideas don’t come from nothing, they come from bad attempts and from repeated improvements.So if we have high aspirations like Picasso and Van Gogh, sometimes we will fall into pain, entanglement and have no idea where to start.Of course this doesn't mean we should treat work perfunctorily. What I mean is to try as much as possible, do more stupid things and then gradually improve.Every bug is an opportunity for the system to learn how it works. Every mistake makes us stronger.Perfection does not exist and is the most vicious psychological warfare
