The big picture provides perspective.
Regularly seeing yourself in the context of the universe—just how small and insignificant you really are—will nudge you back off the ledge.
You are unique. There has never been and will never be another you. Be the best expression of you you can be.
But you are just an infinitesimally small part of the universe. It doesn’t spin around you. It’s mostly indifferent to you. It will go on just fine with or without you.
And maybe that should hurt my ego, but instead it frees me to not take myself too seriously.
Thinking this way can free us to just enjoy the ride and relish our good fortune to have made it onto the stage in our bit part in this grand cosmic extravaganza.
