Usain Bolt has won 9 gold medals in last 3 Olympics and he has run less than 2 mins on the track.

That’s economy of effort…

Usain Bolt ran for less than 115 sec in total in his 3 Olympics career and made $119 Million!

That’s more than $1 Million for each second he ran!

That’s a new unit of speed for the “run” for money… $ 1 Million /sec

But for those 2 mins he trained for 15+ years ! That’s investment…
