Just sharing the entrepreneurial wisdom of billionaire entrepreneur Mark Cuban:

1. Sales come first

No matter what your business, you have to be a salesperson.

“Number one: Sales cures all. There has never been a company in the history of companies that has ever succeeded without sales. Anybody who has ever told you, ‘Don’t worry about sales you can grow it and worry about sales later,’ they are lying to you."

“They will fail, you will fail. You have to be able to sell and do you know who the biggest salesperson in your company has to be? You.”

"Do you know who the biggest salesperson in your company has to be? You."
