It might surprise you, but we humans are not wired to be happy. But we crave it, we need it for our health, and so we have to work on it. But it’s well worth the effort.

Numerous studies have shown that the key to success in life might be as simple as happiness. That the most successful people in life are the happiest and that happiness made them successful and not the other way around.

Happiness triggers all the good hormones in the brain, strengthens the immune system, helps with stress, depression, and anxiety, improves friendships and relationships, and increases optimism and motivation.

So what’s the key ingredient of happiness? Well it’s not stuff, or money, or wealth, or fame, but it might be as simple as one of the other major pillars – kindness.
