I have spent a lot of time over the last six months trying to decide whether to retire or continue working. Thanks to a relatively successful career in finance, if I retire now – at what is a relatively young age (early 50s) – I could do so comfortably. It’s tempting, as I have some big travel plans, but I’m quite worried about being bored and unfulfilled for the next 20-30 years. I also feel I still have something to offer my company and industry. Do you know people who have retired early and regretted it?
