Keeping on top of work tasks and personal to-do's doesn't have to be complicated.
If serial entrepreneur and investor Marcus Lemonis can run multiple businesses using mere notecards, there is hope for the rest of us.
"I have little notecards in my closet, in my basement," Lemonis said. "I'll make a list of the five things I want to get done that day."
The notecard is a promise to himself.
"Without exception, I have to get those five things done," he said.

For Lemonis, this notecard trick is a great way to start your day off on a productive note.
"I don't make lists at the end of the day. I make lists at the beginning of my day," he said. "I always have my knockout list."
As the star of CNBC's "The Profit," Lemonis attempts to save struggling businesses from failure. So those five daily tasks could range from redesigning a business' budget to overhauling its supply chain.
At the end of the day, the entrepreneur finishes his routine by sending his knockout lists soaring.
"They make really cool paper airplanes," he said, smiling.
