Technology should serve people, not the other way around.
The only limit is the one you set for yourself.
Take long walks in stormy weather or through deep snows in the fields and woods, if you would keep your spirits up. Deal with brute nature. Be cold and hungry and weary.
Nothing is a waste of time if you use the experience wisely.
生活的美妙之處在于它永遠不會如你所想的那樣發(fā)展。
