Life & Career Milestones

My path in life has been direct

  • 1.

    Designed and built a machine that picked up electrical signals from the human eyeball to diagnose eye diseases.

  • 2.

    They weren't paying him but he loved it, so he lived off discarded old fruit and veggies.

  • 3.

    Had an epiphany while working as a doctor: told a patient's parents that their son was going to be fine, could easily be treated for pneumonia.

  • 4.

    Everyone in the room burst into tears; he realized what he really wanted to do was "liberate people from what holds them back."

  • 5.

    He thinks he's succeeded at this; people come up to him in the street and tell him his show has improved their lives.

  • 6.

    But he didn't have this epiphany until his mid-forties; says you never know when it will hit you.

  • 7.

    You can't really "decide" what you're going to do with your life until it comes to you, gives your life meaning.

  • 8.

    Says learn the difference between true happiness and fun: you can have a lot of fun and still not be truly happy.
