Growing up in the icy isolation of Hibbing, Minn., Dylan, who was still Robert Allen Zimmerman then, found comfort in the country, blues, and early rock 'n' roll that he heard at night on a Louisiana radio station whose signal came in strong and clear.

In the role of Ziggy Stardust, Bowie seemed in 1972 like a strange alien creature, not so much coming from another planet as from a future age. His purpose: to warn us about a dangerous society where values were to be turned inside out.

I was getting calls in 1970 from teenagers, little girls, and they'd say, 'Oh, I like your stories about so-and-so so much. How old are you? 20?' 'No. Older than that.' '30?' 'No. Older than that.' And they'd hang up.

The greatest impact of 'We Are the World' seems to have been the video, which lets us see the singers take their turns at the microphone without any sense of star ego.

We need to realise that not everyone can take the path to overnight success. Take actors such as Rajkummar Rao and Vicky Kaushal - they have built their work and profile over the years to get to where they are.

In this achievement-based lifestyle, most of us have certain boxes we're checking to make us useful humans. But a lot of things you do as a parent are kinda invisible. There's a lot you achieve - just getting dinner on the table - that are more than making a song.

Yes I have made a lot of money and I have a lot of respect, my films have done well, and I know there are loads of loads of people who look up to me and really love me. I really just thought this is like a strange dream. I have never thought this is a success - I don't have a standard.

The most direct path to achievement whether you're an entrepreneur, a company executive, or a pro soccer player is to be a great performer and a great team member. This is also the secret to a meaningful career and self-fulfillment.
