You could live off of a million dollars for your whole life.... Think about it. If you put that into a low interest savings account (lets say 1% monthly) you will be making $10,000 just from interest alone per month. I plan on retiring at ripe age of 50 haha. Solar panels, no debt, a savings account since I was 16 that won't be touched until retirement, etc. Are all going to help out a lot. Make sure you have enough to mess around with your toys as well, you won't want to retire and sit around all day. That's how you end up with dementia.
