I've built businesses with over $450 million in sales and have helped others generate over $10 billion. Sharing what I've learned.

What’s a six-minute strategy to boost your happiness for six months?

Botox.

According to researchers at Cardiff University, injecting botox to prevent frowning, reduces depression.

For a non-pharmaceutical intervention, smile in the mirror for a few seconds every morning.

Even a fake smile makes you more resilient to stressors.

One of my favorite things to do while sitting at a red light near an intersection is to watch the faces of people turning their cars. Almost all are frowning. They’re focused on not crashing, so maybe that’s a good thing. But, like advice given to meditators, it wouldn’t hurt them to adopt a “half-smile”.

When you see others, even strangers, smile. You’ll appear more likable and less threatening, and you’ll make their day better. Plus, you’ll be happier.

The most effective happiness — and general life improvement — interventions are often the simplest. People create complex systems, products, and programs to make money, not to provide the most cost-effective solutions. It’s like improving your health or appearance. It’s hard to make money telling people to eat real food and exercise daily than it is to sell a bottle of pills or workout gizmo. That’s part the reason I’m writing these lessons — to share the simplest, fastest, easiest ways to improve your life based on my experience and education.

So,

The next stranger you meet,
Or mirror you greet,
Every once in a while,
Smile.
