By steps we may ascend to God. [ Milton ]

Fearless minds climb soonest unto crowns. [ William Shakespeare ]

The movement of the species is upward, irresistibly upward. [ Bancroft ]

It is but a base, ignoble mind that mounts no higher than a bird can soar. [ William Shakespeare ]

Whilst we converse with what is above us, we do not grow old, but grow young. [ Emerson ]

It is not to taste sweet things, but to do noble and true things, and vindicate himself under God's heaven as a God-made man, that the poorest son of Adam dimly longs. Show him the way of doing that, the dullest day-drudge kindles into a hero. They wrong man greatly who say he is to be seduced by ease. Difficulty, abnegation, martyrdom, death, are the allurements that act on the heart of man. Kindle the inner genial life of him, you have a flame that burns up all lower considerations. [ Carlyle ]
