As you get older it is harder to have heroes, but it is sort of necessary.
It is harder to crack prejudice than an atom.
I'm a great believer in luck, and I find the harder I work, the more I have of it.
To love life is to love God. Harder and more blessed than all else is to love this life in one's sufferings, in undeserved sufferings.
I want to be thoroughly used up when I die for the harder I work the more I live. I rejoice in life for its own sake.
George Bernard Shaw
The harder you work, the luckier you get.
