HAPPINESS, LOVE IS THE MASTER KEY
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
Everyone chases after happiness, not noticing that happiness is right at their heels.
Happiness lies in the joy of achievement and the thrill of creative effort.
HAPPINESS, HAPPINESS LIES IN THE JOY OF ACHIEVEMENT
Be more dedicated to making solid achievements than in running after swift but synthetic happiness.
HAPPINESS, DEDICATED TO MAKING SOLID ACHIEVEMENTS
Don't wait around for other people to be happy for you. Any happiness you get you've got to make yourself.
