What about working for 2 years then taking a break to work on side projects and travel for a year. With a high income you can do this; essentially working 66%
I like to work in an office because it gives me two separate worlds (office and home) which is good for my sanity.
Finally, I live in France where the costs of life are quite high and I will not be able to easily find a similar job (there are just a few) so when I retire, this is for good.
I am considering a sabbatical, though.
