A tool is an object used to shorten the distance between a vision and its realization.
Wherever your life ends, it is all there. The utility of living consists not in the length of days, but in the use of time; a man may have lived long, and yet lived but a little. Make use of time while it is present with you. It depends upon your will, and not upon the number of days, to have a sufficient length of life.
Someday perhaps I will go around carrying only a book, a change of clothes, a pen, a water bottle, a folding umbrella, and a little capsule that turns into my livelihood when opened. Rollable hi-res screen and keyboard, tiny computer the size of a cell phone or smaller but as light as a pen, with high-speed satellite connectivity anywhere on the globe. In this world, my sleeping bag, pad and windproof hammock weigh only a pound put together. For half of the year I travel the world, alone and with companions, with a small bag slung over my shoulder like Kwai Chang Caine. We sleep outdoors, travel on trains, and a few days of the week sit some place cozy and create beautiful software or solve interesting problems that improve the world.
