Being self-made is a state of mind, and once you put that mentality to work, your success will come.

A lot of people change for good. Some people just fall off. Just trying to progress in anything, no matter what you're doing, I feel like any progression you make... some people aren't gonna be around you that were around you.

Quotes from the same author

As a technology, the book is like a hammer. That is to say, it is perfect: a tool ideally suited to its task. Hammers can be tweaked and varied but will never go obsolete. Even when builders pound nails by the thousand with pneumatic nail guns, every household needs a hammer.

One of the ways the telegraph changed us as humans was it gave us a new sense of what time it is. It gave us an understanding of simultaneity. It gave us the ability to synchronize clocks from one place to another. It made it possible for the world to have standard time and time zones and then Daylight Savings Time and then after that jetlag. All of that is due to the telegraph because, before that, the time was whatever it was wherever you were.

Even when builders pound nails by the thousand with pneumatic nail guns, every household needs a hammer. Likewise, the bicycle is alive and well. It was invented in a world without automobiles, and for speed and range it was quickly surpassed by motorcycles and all kinds of powered scooters. But there is nothing quaint about bicycles. They outsell cars.

Children and scientists share an outlook on life. If I do this, what will happen? is both the motto of the child at play and the defining refrain of the physical scientist. ... The unfamiliar and the strange - these are the domain of all children and scientists.

It is not true that people who accomplish things don't waste time and that people who waste time don't accomplish things. The very concept is ill-informed. You can't waste time and you can't save time; you can only choose what you do at any given moment.
