Search for the seed of good in every adversity. Master that principle and you will own a precious shield that will guard you well through all the darkest valleys you must traverse. Stars may be seen from the bottom of a deep well, when they cannot be discerned from the mountaintop. So will you learn things in adversity that you would never have discovered without trouble. There is always a seed of good. Find it and prosper.
— Og Mandino

How hard to realize that every camp of men or beast has this glorious starry firmament for a roof! In such places standing alone on the mountaintop it is easy to realize that whatever special nests we make---leaves and moss like the marmots and birds, or tents or piled stone---we all dwell in a house of one room---the world with a firmament for its roof---and are sailing the celestial spaces without leaving any track.
John Muir mountaintop quote

The best an American can look forward to is the lonely pleasure of one who stands at long last on a chilly and inhospitable mountaintop where few have been before, where few can follow and where few will consent to believe he has been.
— George F. Kennan

There is no easy walk to freedom anywhere, and many of us will have to pass through the valley of the shadow of death again and again before we reach the mountaintop of our desires.
— Nelson Mandela

He was the sort of person who stood on mountaintops during thunderstorms in wet copper armour shouting "All the Gods are bastards."
— mountaintop quotation by Terry Pratchett
