There are countless TED Talks. People with exceptional expertise in their field try to teach and summarize what they know in just a few minutes. Well, maybe not exactly—it’s probably more about creating a general understanding of the importance of what they’re saying.

My favorite TED Talks are usually the ones where the goal is some kind of behavioral change—where what they have to say is so revolutionary that you decide to break away from your old habits in everyday life. This can cover everything from entrepreneurship to achieving a personal sense of self-fulfillment.

Here are 6 TED Talks that are sure to pique your interest—and maybe one of them will be the start of a better life for you.
