Hard work brings success, but to do hard work, the machinery must be in good order. You must keep your constitution up, you must have plenty of sleep and you must learn to eat and breathe properly.
No story of success has ever been truly written that did not depict hard work in every line.
Success comes by inches, not by leaps or bounds. Success is the pushing forward each day by hard work.
Burn the candle at one end only and you replace each day what you have burned, by rest, sleep and recreation. By burning the candle at one end only and replacing it fully each day, your candle will not burn out.
Kindness
"A little word in kindness spoken,
A motion or a tear,
Has often healed the heart that's broken
And made a friend sincere."
