Hi,
It is not an easy decision to make and finding what one wants to do post-banking or what transferable skills on has is not always that easy. I worked in banking for about 20 years and have retrained as a yoga instructor. I have recently done an interview on the subject for efinancialcareers which is on my website which I hope might inspire you. You can find it in the "about" section on www.yogiyoga.co.uk. My phone number is on my website if you want to call and chat. It seems like you are getting a lot of valuable advice from this panel. Best of luck!
Erika
