It is easy in the world to live after the world's opinions; it is easy in solitude to live after your own; but the great man is he who in the midst of the crowd keeps with perfect sweetness the independence of solitude.
Ralph Waldo Emerson (1803-1882) U.S. poet, essayist and lecturer.

Solitude is painful when one is young, but delightful when one is more mature.
