You may not think that skateboarding and success have much in common, but there is one thing skateboarders definitely know how to do: get back up.
Influential and innovative pro skateboarder Rodney Mullen is best known for his freestyle skills, but he also has some motivational thoughts in this TED Talk on how the drive of skateboarders can be applied to your own life. Skateboarders crash repeatedly for hours and hours in hopes of landing the perfect trick. It's a great analogy for finding success in your own ventures. Nobody lands a kick-flip the first time they try it.
More importantly, Mullen talks about the factor that makes you get back on the board again. There are a lot of people with the strength and acrobatic ability -- or "gears" -- to take on skateboarding tricks, but without the desire to get back up after getting broken and bruised -- or the "engine" -- you'll never actually succeed at what you're trying to accomplish. Remember, life is full of scraped shins, broken arms, and groin shots. You have to get back on the board.
