I used to replace things the moment they got tired. Slightly dull knife? Buy a new one. Scratchy sweater? Donate it. Phone case with a cracked corner? Order a new one. I switched my mindset a few years ago, and now I get years of extra use out of stuff that used to hit the trash early.

Most things do not die. They just need ten minutes of maintenance.

Start with the obvious

• Sharpen your knives. A $10 sharpener makes a dull knife new again. Most kitchen knives last decades with regular honing.
• Wash your pans properly. A ruined nonstick pan is usually just a pan that needs a better wash and a little oil.
• Replace the shoelaces before you replace the shoes. New laces make old shoes feel fresh.
• Unclog and clean your tools. A drill with a dirty chuck or a saw with resin on the blade works like new after a clean.

Fix before you replace

Before buying a replacement, spend five minutes looking at the problem. Most failures are a loose screw, a clogged filter, or a dead battery. My vacuum lost suction for months and I was about to buy a new one. The filter was clogged. Ten minutes with soapy water fixed it, and it has run fine for a year.

Repair what you can

Learn three basic repairs: sewing a button, tightening a hinge, and replacing a zipper pull. Those three cover an embarrassing number of broken items. I saved a jacket that I loved because I learned to sew a button on properly, and it got two more winters.

Care beats storage

Store things so they do not degrade. Clean and dry items before putting them away. A bike stored wet rusts; a bike stored dry lasts. Wooden handles last when oiled once a year. This is not maintenance for perfectionists, it is ten minutes a month.

The math

Extending the life of what you own from three years to six years halves the cost of owning it, year over year. That is a bigger saving than any coupon, and it is completely within your control.

My wallet is happier, and honestly, I like my stuff more now that I actually take care of it.
