Return on Investment


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 secs in total in his 3 Olympics career and made 119 million dollars! 

That's more than $1 M for each second he ran! 

That's a new unit of speed for the "run" for money... $ 1Million/sec 

But for those 2 mins he trained for 15+ years ! 

That's investment.

Abilene Paradox


On a hot afternoon in Coleman, Texas, the family is comfortably playing dominoes on a porch, until the father-in-law suggests that they take a trip to Abilene [53 miles north] for dinner. 

The wife says, "Sounds like a great idea." 

The husband, despite having reservations because the drive is long and hot, thinks that his preferences must be out-of-step with the group and says, "Sounds good to me. I just hope your mother wants to go." 

The mother-in-law then says, "Of course I want to go. I haven't been to Abilene in a long time."

The drive is hot, dusty, and long. When they arrive at the cafeteria, the food is as bad as the drive. They arrive back home four hours later, exhausted. 

One of them dishonestly says, "It was a great trip, wasn't it?" The mother-in-law says that, actually, she would rather have stayed home, but went along since the other three were so enthusiastic. 

The husband says, "I wasn't delighted to be doing what we were doing. I only went to satisfy the rest of you." 

The wife says, "I just went along to keep you happy. I would have had to be crazy to want to go out in the heat like that." 

The father-in-law then says that he only suggested it because he thought the others might be bored.

The group sits back, perplexed that they together decided to take a trip which none of them wanted. They each would have preferred to sit comfortably, but did not admit to it when they still had time to enjoy the afternoon.



In group think theories, the Abilene paradox theory is used to illustrate that groups not only have problems managing disagreements, but that agreements may also be a problem in a poorly functioning group.
