Tynan has written a couple of times about the habit of shutting down your computer at a certain time everyday. I imagine that a bunch of you - like me - thought about this and decided to start this habit, but regularly find yourself still behind your computer WAY beyond your shutdown time.
Since half a year ago, this never unintentionally happens to me anymore. This is because my computer turns off by itself at my time limit, whether I think about it or not.
So, how does this work? You can use windows task scheduler (this is already installed in your windows PC) to shut down your computer at any time you would like to schedule, whether this is every night, later on weekend days, or only on the second sunday in the month.
Here are tutorials for setting it up:
Mac and Linux probably have a similiar function, or you can install a program that does this for you.
Set this up! It takes 5 minutes to do, and you more than earn it back on the first night you otherwise would have been behind your computer later than you want. If you already succeed in shutting your computer down, this will at least save you effort.
