This world is not for cowards. Do not try to fly. Look not for success or failure. Join yourself to the perfectly unselfish will and work on. Know that the mind which is born to succeed joins itself to a determined will and perseveres. You have the right to work, but do not become so degenerate as to look for results. Work incessantly, but see something behind the work. Even good deeds can find a man in great bondage. Therefore be not bound by good deeds or by desire for name and fame. Those who know this secret pass beyond this round of birth and death and become immortal.
Swami VivekanandaSay, "I can do everything ." "Even if poison of a snake is powerless if you can firmly deny it."
Swami VivekanandaGive up the idea that by ruling over others you can do any good to them. But you can do just as much as you can in the case of the plant: you can supply the growing seed with the materials for the making up of its body, bringing to it the earth, the water, the air, that it wants. It will take all that it wants by its own nature, it will assimilate and grow by its own nature.
Swami Vivekananda
