Sunday motivation: Top leadership quotes by Apple co-founder Steve Jobs

Steve Jobs, one of the co-founders of Apple, left a legacy of revolutionary products. But he also gave wisdom to aspirers. Here are his best quotes.

"I'm convinced that about half of what separates successful entrepreneurs from the non-successful ones is pure perseverance."

"My favorite things in life don't cost any money. It's really clear that the most precious resource we all have is time."

"My model for business is The Beatles. They were four guys who kept each other's kind of negative tendencies in check. They balanced each other, and the total was greater than the sum of the parts. That's how I see business: Great things in business are never done by one person, they're done by a team of people."

"Sometimes when you innovate, you make mistakes. It is best to admit them quickly, and get on with improving your other innovations."

"Your work is going to fill a large part of your life, and the only way to be truly satisfied is to do what you believe is great work. And the only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle. As with all matters of the heart, you'll know when you find it."

"Innovation distinguishes between a leader and a follower."

"Bottom line is, I didn't return to Apple to make a fortune. I've been very lucky in my life and already have one. When I was 25, my net worth was $100 million or so. I decided then that I wasn't going to let it ruin my life. There's no way you could ever spend it all, and I don't view wealth as something that validates my intelligence."
