About this course

Ever told yourself you'll save money, and then somehow ended up splurging? Or planned a healthy dinner, only to find a pizza box at the door?

It's not that you're lacking willpower. It's more like you're trying to steer a modern life with an old brain. And honestly, nobody ever taught you the rules for how your mind tends to behave.

I'm Dan Ariely, a Professor in behavioural economics. For years, I've run experiments to spot the subtle biases that shape the decisions we think we're making on purpose.

This course is the guide you probably wished you had earlier. You'll get a set of research-backed tools that help you stop wrestling with your own brain and start working with it.

Along the way, you'll learn how to:

Make Better Decisions: Spot the hidden factors influencing your choices, then use straightforward strategies to push back against them.

Master Your Money: Get to grips with the odd psychology behind spending, saving, and investing, so you can grow real wealth over time.

Improve Your Productivity: Figure out why procrastination keeps happening, and set up a system that helps you focus on what actually matters.

Build Better Habits & Relationships: Understand what makes habits stick, and learn how to have more thoughtful, productive conversations.

Find Real Happiness: Move past quick thrills and get clearer on what creates long-lasting satisfaction and a more grounded life.

By the end, you'll be able to act like a choice architect in your own world. In other words, you;ll design your environment so the smarter option becomes the easier one.

Stop fighting your brain. Start understanding it. Enrol today.
