Know your why, no matter what it is, and stay focused on it.

“You’ll never succeed without me.” That’s the insult a young Barbara Corcoran — a real estate investor and Shark Tank regular — received from her long-term boyfriend and business partner. He dumped Barbara for her secretary, and these were his parting words. “I knew I would rather die than let him see me fail,” she told a reporter at USA Today.

“His sage advice made me more determined to become a big success, and I worked harder than ever to prove him wrong.”

So take the time to figure out your why, if you haven’t already, and then keep it in mind as you pursue your dreams.
