There comes a time in many people's lives when they feel they have nothing to prove any more. They've had their demanding, successful career, and now they want more quality of life - but they don't want to disappear into retirement.
Principal coach at Coaching Partners, Patti Gwynne, says: "It's all about life design. There comes a stage when you've been up the career ladder and don't want the pressures that a six-figure salary brings.
"Perhaps you want more social engagement or to spend more time with family, but you're not ready to retire completely."
Gwynne coaches many baby boomers who want to have what's called an "encore career", which, she says, is often something that someone has a personal connection to. "Say someone has been a hobby photographer for years - their encore could be in freelance photography."
Gwynne herself has embarked on an encore career. From managing 40 staff in an IT company, she realised that although she was earning well, she wasn't getting a lot of satisfaction.
