Slight off-topic, but what improved my life was buying good quality products. For instance, I used to use a cheap $2 nail clipper from the drug store. Now I use a Seki nail clipper imported from Japan. Sure it's 10-15x more expensive, but it's largely worth it. I've found that for items that you're going to use for decades, often it's worth it to spend a premium for higher-quality ones.
