Quote from : Crave Book

Destiny was a machine built over time, each choice that you made in life adding another gear, another conveyor belt, another assemblyman. Where you ended up was the product that was spit out at the end—and there was no going back for a redo. You couldn‟t take a peek at what you‟d manufactured and decide, Oh, wait, I wanted to make sewing machines instead of machine guns; let me go back to the beginning and start again. One shot. That was all you got.
