As you can imagine, Shark Tank star Kevin O’Leary is beyond busy. The multi-millionaire mutual funds mogul says his phone rings “just about every 30 seconds” and his email inbox is overflowing, but he doesn’t care.

“Not until I achieve the three daily goals that I set for myself the night before,” he recently told Entrepreneur from the Culver City, Calif. set of Shark Tank. “Each has to be accomplished before I take any inbound calls or send any emails, and I strictly follow that simple process daily, without fail.”

And without exception, barring a catastrophic emergency, as the 61-year-old entrepreneur put it. “Whether it’s family or business or something personal, I work on nothing else, whatever it may be,” he says. “My attitude is, until those three goals are done, nobody gets my time or attention.”
