Invest in quality products you need and actually use.
The older I've become, the more I've focused on owning quality items and products. I don't just want anything. I want something that serves the purpose, and serves it well — and is necessary to my life.
You may think this results in spending more money, but it doesn't. One hundred one-dollar items gets you to the same place as one one-hundred-dollar item. But only in terms of money — you will have a higher net-benefit with the quality item vs. the myriad of "junk".
I think this is why I like Apple products so much.
Yes, they are outrageously expensive — and growing with each passing day. But they're also well-made, high-quality products I know will last. And I know they will serve a clear purpose.
