After 43 years of the Glastonbury Music Festival, and after much negotiation, the Rolling Stones have finally played the famous pyramid stage. It happened on Saturday, started with Jumping Jack Flash and ended with (can't get no) Satisfaction. What caught my attention though, was the headline that Sir Mick Jagger had spend many hours "intently watching DVDs of previous headline performances."

I was impressed that despite his experience as a performer, he still saw the need to learn and improve, even after 50 years in the industry and some of the most lucrative and successful live tours of any band in history.

It reminds me of the following quote from L Carte:

Only those who have learned a lot are in a position to admit how little they know.

How many professionals and leaders in your organisation retain that same commitment to continue learning in order to be the best the can be?

Jagger, a former London School of Economics student, still exhibits intellectual curiosity, so I'll give him the last word:

"Everyone wants to have done more things in their lives. It is a slightly intellectually undemanding thing to do, being a rock singer, but, you know, you make the best of it."
