"Many things are improbable, only a few..." - Quote by Elon Musk

“I started SpaceX with the expectation of failure.”

“If you think back to the beginning of cell phones, laptops or really any new technology, it's always expensive.”

“I'm reasonably optimistic about the future, especially the future of the United States - for the century, at least.”

“Breathe in the sweet air of limitless possibility, and make life as rich as you know it can be.”

“Oh, yesterday, that one, we all cry out. Oh, that one! How rich and possible everything was! How ripe, ready, lavish, and filled with excitement--how hopeful we were on those summer days, under the clean, white racing clouds. Oh, yesterday!”

“You are full of wonderful possibilities. Do something with them. The most painful regrets, those which never go away, are regrets of things not done, things never attempted.”

“In spite of all of the things, the issues, that we may be confronting today, I'm very hopeful, very optimistic about the future.”

“When the outlook isn't good, try the uplook - it's always good!”

“Choose to be optimistic, it feels better.”
