Keep a grateful journal. Every night, list five things that happened this day that you are grateful for. What it will begin to do is change your perspective of your day and your life. If you can learn to focus on what you have, you will always see that the universe is abundant; you will have more. If you concentrate on what you don't have, you will never have enough.
The recurrence of a phenomenon like Edison is not very likely. The profound change of conditions and the ever increasing necessity of theoretical training would seem to make it impossible. He will occupy a unique and exalted position in the history of his native land, which might well be proud of his great genius and undying achievements in the interest of humanity.
All that we are is the result of what we have thought. If people speak or act with evil thoughts, pain follows them. If people speak or act with pure thoughts, happiness follows them, like a shadow that never leaves them.
Without books the development of civilization would have been impossible. They are the engines of change, windows on the world, "Lighthouses" as the poet said "erected in the sea of time." They are companions, teachers, magicians, bankers of the treasures of the mind, Books are humanity in print.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
Young people: I understand this is important to you, but as you be thinking about climate change, the economy and jobs, war and peace, maybe way at the bottom you should be thinking about marijuana.
Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it.
Work is love made visible. And if you cannot work with love but only with distaste, it is better that you should leave your work and sit at the gate of the temple and take alms of those who work with joy. For if you bake bread with indifference, you bake a bitter bread that feeds but half man's hunger. And if you grudge the crushing of the grapes, your grudge distils a poison in the wine. And if you sing though as angels, and love not the singing, you muffle man's ears to the voices of the day and the voices of the night.
