If you want to get advice on being an entrepreneur, listen to Mark Cuban. The billionaire businessman gives out such advice on his reality show “Shark Tank.” Mark Cuban is one of a panel of judges who decide if a startup is worth the investment. On the last installment of the show, he said that resilience is one of the best traits he sees in people starting new companies when reviewing Big Bee, Little Bee .

But Mark Cuban also said that the worst trait is what he calls “inventor-itis.”

Earlier this month Jewish Business News reported on how Mark Cuban is said to be thinking of leaving the hit reality TV show “Shark Tank.” It has been rumored that the reason for his leaving is the success of Cuban’s new business venture the Cost Plus Drugs company.

When speaking to Amy Leinbach, the founder of children’s tool company Big Bee, Little Bee, Mark Cuban said, “One of the great traits of any good entrepreneur is resilience, and you’ve certainly shown that,” Cuban told. “But you also have ‘inventor-itis,’ which is one of the worst traits an entrepreneur can have.”

So, what did Mark Cuban mean by “inventor-it is?” Well, in the case of Big Bee, Little Bee, it means offering too many products. Cuban feels that if you created something worth promoting stick to it and don’t cloud things with other items because it makes it seem that you don’t have enough faith in any one product.

Shark Tank, in which would be entrepreneurs try to get backing for their ideas, has been on the air since 2009.
