You've got plenty of money, you're living on 1% of your savings, which is great - controlling expenses is significant.

You should be able to invest the money with the goal of beating inflation and grow your pile. There's people who retire with a lot less. There's tools to help, where you can play with the numbers, investment returns, inflation rates, etc.

It's difficult to predict the future. You might wish you had more money a couple of decades from now, or you might get hit by a bus next year and wish you had lived it up more when you had the chance. Eventually the stress of your current job is likely to affect your health. It takes a while to get over being burnt out.

The safest option might be to look at your money as a wonderful cushion, giving you options that others only dream of. You can find a different job that you like, even a lower paying job preserves a lot of your savings. You can take time off, maybe doing something along the way that looks good on your resume. You can work on and off. You can change careers. Maybe figure out what you'd want to do if money were not the object. You are way ahead of the game. The world is your oyster!

It can take a while to figure these things out. Best of luck!
