1. The time it takes to do some of these things would be better spent working a second job.
2. For many commonly used household items, it costs MORE to fix it than replace it.
For many small appliances this is true plus they weren't made to be taken apart to be fixed.
For larger appliances there is a law of diminishing returns. I fixed the dryer three separate times, replacing the heating coil, the drum rollers and the drum belt all for under $150 total. The dryer is 25+ years old and owes it's continued life to EBay. A new replacement would cost way more than the original even with repair costs added.
Agreed. And #22. Relax by candlelight. Candles are expensive. You could probably run an LED bulb for a year on what a candle cost.
