Mark Cuban has a lot to say about success in business. Which quote is your favorite? Post it to social media and include my Twitter handle and the one for Inc. Include a note about why it is inspires you.

1. "What I've learned is that if you really want to be successful at something, you'll find that you put the time in. You won't just ask somebody if it's a good idea, you'll go figure out if it's a good idea."

2. "Sweat equity is the most valuable equity there is. Know your business and industry better than anyone else in the world. Love what you do or don't do it."

3. "Work like there is someone working 24 hours a day to take it away from you."

4. "Treat your customers like they own you. Because they do."

5. "It's not about money or connections-it's the willingness to outwork and out-learn everyone... And if it fails, you learn from what happened and do a better job next time."

6. "It doesn't matter how many times you fail. You only have to be right once and then everyone can tell you that you are an overnight success."

7. "What does it take to be a successful entrepreneur? It takes willingness to learn, to be able to focus, to absorb information, and to always realize that business is a 24/7 job where someone is always out there to kick your ass."

8. "The thrill of victory in business blows away the thrill of victory in sports. Business is a sport 24/7/365."

9. "Once you have found out what you love to do, there is only one goal: to be the best in the world at it."

10. "It's not in the dreaming, it's in the doing."

11. "Learn to sell. In business you're always selling--to your prospects, investors and employees. To be the best salesperson put yourself in the shoes of the person to whom you're selling. Don't sell your product. Solve their problems."

12. "Time is more valuable than money."

13. "What makes a good salesperson? Let me be clear that it's not the person who can talk someone into anything. It's not the hustler who is a smooth talker. The best salespeople are the ones who put themselves in their customer's shoes and provide a solution that makes the customer happy."

14. "What I do know, at least what I think I have learned from my experiences in business, is that when there is a rush for everyone to do the same thing, it becomes more difficult to do. Not easier. Harder."

15. Make your product easier to buy than your competition, or you will find your customers buying from them, not you."

16. "Be a yardstick of quality. Some people aren't used to an environment where excellence is expected."

17. "It doesn't matter how many times you fail. It doesn't matter how many times you almost get it right. No one is going to know or care about your failures, and neither should you. All you have to do is learn from them and those around you because ... all that matters in business is that you get it right once. Then everyone can tell you how lucky you are."

18. "You gotta grind."

19. "Forget about finding your passion. Instead, focus on finding big problems."

20. "Don't get caught up in how many hours you work. Judge success based on having goals and measuring your results. Hard work, and lots of it, is certainly needed, but focus on what you get done."
