On Digital Minimalism.
Oftentimes, when you buy a new PC, it comes preloaded with applications. Some of them are essential, like an anti-virus, and some of them are not. Over the years I’ve come to realize that the responsiveness of your device (it doesn’t necessarily have to be a computer, it can be a mobile phone or a tablet, too) depends on how many applications you have installed. It is especially true for mobile devices, where applications are often started at boot and remain in the memory even if they are not used, draining battery power.
My general rule is to always ask myself if I am really going to use the app I am about to install very often or just occasionally. If the answer is: “No, I don’t really need this app.”, I don’t install it no matter how great the hype is over it.
