    Viktor Frankl answered this question. The meaning of life is a life with meaning.
    The Three Sources of Meaning
    By creating a work or doing a deed (Creative Values): You find purpose through your contributions, actions, career, creative projects, or goals you accomplish in the world.

    By experiencing something or encountering someone (Experiential Values): You find purpose by experiencing goodness, truth, beauty, nature, or culture, and by loving another human being deeply.

    By the attitude we take toward unavoidable suffering (Attitudinal Values): You find purpose in how you handle hardship, tragedy, or a difficult fate with courage, dignity, and inner strength when suffering cannot be changed.

    Questions asked:

    What does the common good actually mean and how do we build towards it?
    What do we owe each other as humans?
    If you could design a better world for humans from scratch, what’s the first rule?
    What is a hope you have for humans in the next 10 years?
    What is the biggest barrier to human thriving?
    How do we build systems that influence the good in each other?

    The “Biggest barrier to Thriving” is the most simple yet complex thing in your life. That thing is what is BETWEEN YOUR EARS. The way you approach and view your creativity, and perception is literally EVERYTHING. The ‘man on the mountain ‘ can’t show you – though it’s possible he/she MIGHT get you closer. The best bet (as I can see it) is to simply be open to the moments in front of you, and to be as honest with yourself and the world as you can. Seems like a good start!🙂

    Capitalism, it’s capitalism. That’s why everything sucks right now. All the money is at the top and we’re all struggling to survive.

Why We Should Design Cities Like Disney | Zach DeBoer | TED

Where you live shapes your relationships, your emotions and even how long you live, says community designer Zach DeBoer. After studying what a century of building cities around cars has done to downtowns in the US, he turned to lessons from some of the most walkable, carefully designed streets in the country: the ones inside Disney theme parks. With ideas ranging from narrower roads to buildings that pull you around the next corner, he offers a practical guide to turning ordinary downtowns into magical places people want to explore.
