I got this idea from my friend ngeor:
Nowadays, I am writing code everyday for at most 30 minutes against a GitHub project. This is outside work hours of course. The important thing is to never exceed 30 minutes. If you spend too much time coding, you’ll end up missing out on other things in your daily routine. If you don’t code at all, you’ll miss it. I find half an hour to be a good balance. Keeps the appetite going, doesn’t leave you hungry, doesn’t leave you full either.
