Dreams, in their essence, include risk. This risk could be physical danger (often true in climbing big mountains like Everest), or it could be financial (leaving a comfortable job and pouring your life savings into a business venture), or it could be emotional (like the feelings of loss and questioning that comes with losing friends and coworkers to climbing accidents).
Take risks in your life in the pursuit of your dreams, and support the ones you love when they take risks.
Weigh risk carefully, and once you decide a risk is manageable and necessary in the pursuit of your dreams, take it.
Support the ones you love when it is their moment to risk.
