Constant development is the law of life, and a man who always tries to maintain his dogmas in order to appear consistent drives himself into a false position.
No work or love will flourish out of guilt, fear, or hollowness of heart, just as no valid plans for the future can be made by those who have no capacity for living now.
The credit belongs to those who are actually in the arena, who strive valiantly; who know the great enthusiasums, the great devotions, and spend themselves in a worthy cause; who at best know the triumph of high achievement; and who, at worst, if they fail, fail while daring greatly, so that their place shall never be with those cold and timid souls who know neither victory nor defeat.
We are all inventors, each sailing out on a voyage of discovery, guided each by a private chart, of which there is no duplicate. The world is all gates, all opportunities.
Take hold of your own life. See that the whole existence is celebrating. These trees are not serious, these birds are not serious. The rivers and the oceans are wild, and everywhere there is fun, everywhere there is joy and delight. Watch existence, listen to the existence and become part of it.
