    Everybody should create a practice repo▲24

    Hi everybody, I personally found the best way to motivate yourself to program everyday is by creating a practice repo and by uploading anything you code up that day into this repo. This is a great way to stay consistent seeing the bright green light up every time you push your code. It's very addicting and satisfying, and has definitely made me a better programmer over the past few months.
