The document discusses three keys to happiness: gratitude, savoring life, and finding meaning in work. Gratitude can increase happiness, health, relationships and productivity. It is recommended to keep a gratitude journal and read it daily. Savoring life means defining values, being true to yourself, knowing passions, giving to others, showing kindness, releasing things, spending time with others, and playing. Finding meaning in work involves knowing what you want from work, taking initiative, remembering your purpose, and changing your attitude rather than your job.
