Hold your head high
"In this world, the optimists have it, not because they are always right, but because they are positive. Even when they are wrong they are positive, and that is the way of achievement, correction, improvement, and success. Educated, eye-open optimism pays." - David Landes
"The essence of optimism is that it takes no account of the present, but it is a source of inspiration, of vitality and hope where others have resigned; it enables a man to hold his head high, to claim the future for himself and not to abandon it to his enemy. "
- Dietrich Bonhoeffe
