Depends. Using the "4% rule" you should be able to drawn down $40k/year, without depleting your capital, so if you can live on that then in theory the answer is yes. There are various provisos with using the 4% rule but I won't go into them here. A couple of other options:

1) You could retire from full-time work and do the odd contract.

2) Set up a little sideline. It wouldn't have to make much as you already have a lot saved.

3) Part-time job at Starbucks (or similar). This is also known as Barista FIRE (FIRE is Financial Independence Retire Early). The idea is in USA you'd get the Starbucks free health care, and a little income, plus it might be fun, if somewhat hectic.

4) You really do need to think about what you would want your retired life to look like. "Not work" will only be enough to take you through the "decompression zone", not beyond.

One final point. Things change. You change. Life happens. At some point you might want to get married, have ten kids, and build a house in the countryside. Who knows. I think that's why keeping your skills honed and brain working in "retirement" is probably a good idea.
