'exp that makes u doubt your skills'

Nearly all popular repos on GitHub.

Probably because more than one person is working on it, don't worry

@ImNotAlfred so who are you then?

@lucaIO Not Alfred ;)

@HAlex absolutely true. But code quality is something one person can provide aswel. 🙂

Again: Rome wasn't built in a day.

This goes both for the projects themselves, as well as for the quality of the code from the devs behind them. It takes a lot of time, practice, and dedication to get to those heights.
And even then, what you see in their commits is actually tons and tons of hours of writes and rewrites on top of more rewrites, until they are satisfied with it.
Until the next commit.
