Dwayne Johnson

As a strong advocate for hard work and perseverance, Dwayne 'The Rock' Johnson has expressed the importance of setting goals for his children.

He said: "By five, you'll be looking people in the eye when you firmly shake their hand. By eight, you'll know how to fish, drive daddy's pick-up truck, and do cardio. And by 10, you'll be able to directly say to people, 'Great job, I like it a lot, but let's see how we can make it better."
