Be more dedicated to making solid achievements than in running after swift but synthetic happiness.
HAPPINESS, DEDICATED TO MAKING SOLID ACHIEVEMENTS
Everyone chases after happiness, not noticing that happiness is right at their heels.
To find out what one is fitted to do, and to secure an opportunity to do it, is the key to happiness.
HAPPINESS, SECURE AN OPPORTUNITY TO DO IT
Happiness doesn't depend on any external conditions, it is governed by our mental attitude.
Happiness is beneficial for the body, but it is grief that develops the powers of the mind.
HAPPINESS, GRIEF THAT DEVELOPS THE POWER OF THE MIND
