Look around you

 Consider the work you do each day.

 Think about how you could do it just a little bit better.

In a marathon race, each step the winner takes is just a little bit longer and a little bit faster than each stride taken by the 100th place finisher. Yet over the course of the race, that small difference adds up in a big way.

 Do just a little bit more today, and tomorrow too, and each day after that.

  Anyone can make just a small improvement, and that can make a big, big difference.
