I just finished putting a new roof on my house, which involved special details that I had to invent and fabricate myself. I also fixed my pants, which ripped frequently. About ten years ago, I was very depressed. Half my house is workshop area, and I could barely walk through the clutter. I decided to take up art metalwork, a job I had really enjoyed, but not made a living at. At first, I was pretty clumsy, and had to learn to use worse eyesight, but I took the time to fix my mistakes and was happy with the results. That was the beginning of recovery.
When I don't have tools, I feel crippled. With them, I usually can fix anything from a kettle to a car, often starting with a free item. This really reduces my need for cash.
I don't envy kids today with their 3-D printers. It is important to get your hands on the material itself and feel it change. I did a lot of work in advanced composites because of what they can do, but I didn't like working all week on a tool, and then just using it to shape a soft mass that would then harden into usefulness.
