The great heroes and the souls who have really done something worthwhile in the world have begun their life with sacrifices. Sacrifice of comfort, sacrifice of convenience, sacrifice of pleasure, of merriment, of joy. There is hardly one among them that you find who did not have to pay a great price to have arrived to that attainment. The higher the attainment the greater the sacrifice it asks. But the one who understands keeps his object always higher than the sacrifice he makes.
