Go katas

Katas (形) are practiced in martial arts as a way to memorize and perfect the movements being executed. Let’s try the same with code. The approach is pretty low-tech. It’s a list of packages that you should be rewriting from scratch or at least partially. There’s a command to visualize your progress:

> go run cmd/katas.go
Kata                                                       Last done       Count
----                                                       ---------       -----

It’s important to practice regularly, to create a habit. Start by taking baby steps, e.g. 15 minutes a day. After some time it will require much less will power, it will become natural for you. 🥋
