Establishing a business empire from scratch takes strong entrepreneurship and leadership skills. There are some very influential people in business who have mastered and implemented those tough tactics and are world-renowned today. Today, we take those powerful women who have changed the landscape of the business world and understand their lessons on leadership.

1. Persistence is the key to getting results: “Whenever I feel bad, I use that feeling to motivate me to work harder. I only allow myself one day to feel sorry for myself. When I’m not feeling my best, I ask myself, ‘What are you gonna do about it?’ I use the negativity to fuel the transformation into a better me.”

– Beyoncé Knowles, singer

2. Tap into your area of expertise: “The reason I’ve been able to be so financially successful is my focus has never, ever for one minute been money.”

– Oprah Winfrey, actress

3. Think outside the box: “Always aim high, work hard, and care deeply about what you believe in. And, when you stumble, keep faith. And, when you’re knocked down, get right back up and never listen to anyone who says you can’t or shouldn’t go on.”

– Hillary Clinton, politician

4. Don’t be afraid of failure: “You will never truly know yourself, or the strength of your relationships, until both have been tested by adversity. Such knowledge is a true gift, for all that it is painfully won, and it has been worth more than any qualification I ever earned.”

– J.K. Rowling, novelist

5. Inspire by empowering others: “Empowering those around you to be heard and valued makes the difference between a leader who simply instructs and one who inspires.”

– Adena Friedman, businesswoman
