This is by Nelson Mandela. Will Smith also has a great story about this concept. When he was a kid, his dad asked him and his brother to build a brick wall. This task seemed crazy at first – a whole brick wall? How do they even start? The answer was to lay the first brick – as perfectly as possible. The next day, lay the 2nd brick – as perfectly as possible. Pretty soon, he was making real progress on the brick wall. At the end of the summer, it was done.
Taking small steps everyday will bring your from impossible done. But it is often unrewarding work. It seems like you have so far to go! Keep making taking those incremental steps, and you’ll get farther than you think you could at the very beginning.
