Putting yourself first is not selfish. Quite the opposite. You must put your happiness and health first before you can be of help to anyone else.
Simon SinekPushing yourself to be the best is unsustainable. Simply push yourself to be better than the day before.
Simon SinekI go into every meeting, into every room and for every speech understanding the standard deviation, the Bell Curve. I know there are about 10-15 percent of people in the room, who say, "I've been trying to say this for years. Finally. I agree. Yes, yes, yes." I know there are about 15 percent of the people in the room who think I'm an idiot, who think I don't know what I'm talking about, who think I'm naive or I have oversimplified everything. The majority who are open to the ideal.
Simon SinekGreat leaders don't need to act tough. Their confidence and humility serve to underscore their toughness.
