What does it take to run a successful business? Who would know better than a successful entrepreneur? For a little inspiration, here’s a compilation of insight from some of the most successful entrepreneurs out there:

On the Idea:

“If you’ve got an idea, start today. There’s no better time than now to get going. That doesn’t mean quit your job and jump into your idea 100 percent from day one, but there’s always small progress that can be made to start the movement.” – Kevin Systrom, CEO & Co-founder of Instagram

“So often people are working hard at the wrong thing. Working on the right thing is probably more important than working hard.” – Caterina Fake, Co-founder, Flickr and Hunch

On Standing Out:

“Risk more than others think is safe. Dream more than others think is practical.” – Howard Schultz, CEO of Starbucks

“Don’t be intimidated by what you don’t know. That can be your greatest strength and ensure that you do things differently from everyone else.” – Sara Blakely, Spanx

“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.” – Mark Cuban, Entrepreneur

On Success:

“The secret to successful hiring is this: look for the people who want to change the world.” – Marc Benioff, CEO of Salesforce

“I’m convinced that about half of what separates the successful entrepreneurs from the non-successful ones is pure perseverance.” – Steve Jobs, co-founder and CEO of Apple

“Timing, perseverance, and ten years of trying will eventually make you look like an overnight success.” – Biz Stone, co-founder of Twitter.

On the Self:

“True leadership stems from individuality that is honestly and sometimes imperfectly expressed… Leaders should strive for authenticity over perfection.” – Sheryl Sandberg, COO, Facebook

“People respond well to those that are sure of what they want.” – Anna Wintour, editor-in-Chief, American Vogue
