I don’t see retirement as a lack of work, rather the financial freedom to do what I want. That may well include work but I will choose to do it rather than needing to do so to pay bills.
Iam a freelancer so pick and choose which roles I do but at present I need to work to pay bills. This also allows me to plan for the future as I see fit, save more or less depending on how much I’m earning and what my goals are. I can even choose to take several months off if I choose and fit work around my lifestyle instead of the other way round.
