I like the last three responses as they are an argument and my thought about not retiring. I too enjoy what I do, look forward to the start of tax season, finishing CEs before the start, and catching up with old friends/clients. I've said to myself, be careful what you wish for in retirement, with so much leisure time, would I really make good use of it? Crossword puzzles are not my thing and as much as I love TV I run out of stuff to watch now. When I travel I can't wait to get home and my 4 car garage is meticulously organized, could eat off the epoxied floor. There is nothing left for me to fix other than changing watch batteries and if I work out anymore I will burn out my Fitbit.
So staying in the business may be a good fit for good health and mental fitness for me. Really makes you think....65, 70, 75 years of age is not old at all, as long as you think young, keep moving and enjoy work and life. Who has it better than us?
