I have a 90-day rule. If I have something and I haven't used it in 90 days, I probably don't need it and get rid of it (sell it, give it away, throw it out).

I have a 90-day rule. If I have something and I haven't used it in 90 days, I probably don't need it and get rid of it (sell it, give it away, throw it out). This tends to keep my life de-cluttered and "focused". It also keeps me from waisting money on stuff I don't need. "Am I really going to be still excited about, and benefit from, using this widget I want to buy in 90 days or not?" I've lived like this for about a decade and I highly recommend trying it. There are exceptions of course. Seasonal items like clothing, mountain bike, etc... Books too as mentioned in the essay. Having a library of coding books on-hand is not only reassuring, but has helped me save significant time solving a problem, even if I only rarely use the book. And I don't think it's a good idea throwing out your old money either. ;)
