Mark Cuban is a whiner. And that’s exactly why he’s successful.

In his book “How To Win At The Sport of Business,” Mark Cuban says,

“I’m a whiner. I guess I have to finally admit it. I took a look back at the way I have lived my life, and I can’t come to any other conclusion.”

When Mark Cuban was in high school, for example, he whined about not being able to take business classes.

So, he decided to take classes at the University of Pittsburgh instead.

When Mark Cuban was hanging out with his friend, they both whined that they couldn’t listen to any hometown sports in Dallas.

So, they started AudioNet.

When Mark Cuban was sitting in attendance at a Mavericks basketball game, he whined that there wasn’t enough energy or entertainment. Cuban thought he could do a better job.

So, he bought the Mavericks.

In this book, Cuban says,

“I’m sure there have been many other things I have whined about in the past, and many more that I will whine about in the future. What I don’t understand is why so many people think whining has a negative connotation. I don’t. Whining is the first step toward change. It’s the moment when you realize something is very wrong and that you have to take the initiative to do something about it… People who don’t whine are punching bags. They just go about their days, their jobs, their lives, knowing there is nothing they can do to change a darn thing, so why say a word? They see no reason to whine because they know they are incapable of effecting change. Call me a whiner any day.”

Mark Cuban is a whiner. And you should be too.
