Mick Jagger admitted on Friday he has found his career in the Rolling Stones "intellectually undemanding" and sometimes wishes he had stuck to his original idea of becoming a teacher.
Jagger, who will front the Stones in their first ever appearance at Britain's Glastonbury festival on Saturday, said he had considered other career options such as being a journalist or a dancer, although that would have involved "too many injuries".
The 69-year-old, who was still a student at the London School of Economics when the Stones were starting out, said in a BBC interview: "A schoolteacher would have been very gratifying, I'm sure.
"There are millions of things you would have loved to have done, a politician, a journalist... I thought of being a journalist once.
"All these things you think of when you're a teenager, you can think, well, I would have liked to have done that but that's completely pointless," he added.
"But I don't feel frustrated for a lack of control at all and I'm very pleased with what I've done.
"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."
