I want to ski down Mount Cho Oyu in the Himalayas when I am 85, descending from a height of 8,201 meters.
I've learned through my own experiences that working toward an objective in your life can change who you are.
Just keep challenging yourself. I think that's a great thing. 
It's important to set your own goals and work hard to achieve them.
It's important to have a dream no matter how old you are.
