This is how to work smarter not harder:

• Do Less, Then Obsess: As Mark Twain quipped, “Put all your eggs in one basket — and watch that basket!”
• Use The Learning Loop: Push yourself now and your job gets easier later.
• Feel Passion & Purpose: You don’t have to play in the NFL or be the next Beyoncé to feel passionate about your job. And purpose can even involve elephant poop.
