Mark Cuban business quotes
It's hard to woo someone to run against Donald Trump, even Mark Cuban
#1: "I still work hard to know my business. I'm continuously looking for ways to improve all my companies, and I'm always selling. Always."
#2: "When you've got 10,000 people trying to do the same thing, why would you want to be number 10,001?"
#3: "Because if you're prepared and you know what it takes, it's not a risk. You just have to figure out how to get there. There is always a way to get there."
#4: "Go out there and get rich. Get so obnoxiously rich that when that tax bill comes, your first thought will be to choke on how big a check you have to write."
#5: "In the past, people used to tell me to shut up a bit. But what I believe is to put out your opinion and let everyone else react. If I'm wrong, I'm wrong."
#6: "I've learned that it doesn't matter how many times you failed. You only have to be right once. I tried to sell powdered milk. I was an idiot lots of times, and I learned from them all."
#7: "Work like there is someone working 24 hours a day to take it all away from you."
#8: "Forget about finding your passion. Instead, focus on finding big problems."
#9: "It's not about money or connections -- it's the willingness to outwork and outlearn everyone when it comes to your business. And if it fails, you learn from what happened and do a better job next time."
#10: "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."

"I would like for there to be an independent Republican candidate because I can't support Trump and I can't support Clinton," Kristol told CNN's Jake Tapper.
In an email to The Post, Cuban wrote of Trump, "He could come after me all he wanted, and he knows I would put him in his place. All that said, again, I don't see it happening. There isn't enough time."
Cuban is probably right. The Republican National Committee is already coordinating strategy and its considerable resources with Trump's camp as the presumptive nominee.
Even the brief, weeklong division between Trump and House Speaker Paul Ryan now appears to be moving closer and closer to unity.
