Who are some of your favorite motivational speakers/authors?

I always liked Jim Rohn, some of his quotes

“Formal education will make you a living; self-education will make you a fortune.“
“Never wish life were easier, wish that you were better.“
“If you don't design your own life plan, chances are you'll fall into someone else's plan. And guess what they have planned for you? Not much”
“You don't get paid for the hour. You get paid for the value you bring to the hour.”
“The more you know the less you need to say.”
“Character isn't something you were born with and can't change, like your fingerprints. It's something you weren't born with and must take responsibility for forming.”

Stephen Covey is another I like

“Be a light, not a judge. Be a model, not a critic.“
“Any time we think the problem is “out there,” that very thought is the problem.”
“Most people do not listen with the intent to understand; they listen with the intent to reply”
“If I really want to improve my situation, I can work on the one thing over which I have control - myself”
