I really don't like dressing in work clothes. Anything more than shorts and a tee shirt is too much for me.
Can confirm. Dressing like a broke college kid every day is pretty great.
A lot of the other stuff, though, is not what everyone seems to think it will be. I still know what day of the week it is, because I still have kids in school and I'm still involved in a variety of community activities. I also don't sleep in very often, for the exact same reasons. Grocery shopping at 9am this morning was pretty sweet, that part is totally true. Also, Sunday evenings are not stress-inducing anymore because I have nothing to dread.
But my retirement is not the lazy life of leisure some people imagine it will be. At least for me, there has been a very limited amount of napping and sleeping late. I don't watch television. I don't go fishing, or drink beer all day, or go days and days without engaging with society. I'm still doing stuff, it's just not stuff I have to do from the inside of a cubicle. On the bright side, it's stuff I want to do and not stuff I have to do, so I don't really mind being busy.
Early retirement doesn't absolve you of all responsibility, the way a bunch of people in this thread seem to think it will. If anything, it makes you more responsible, not less, because it forces you to identify what you're going to do with your time and your life instead of just blindly following orders day in and day out. You have to decide what you're going to do and then you have to do it, because you said you would, and it reflects poorly on you as a person to not do so. In some ways, being a corporate drone is easier. Just show up every day and do what they tell you, and take home money. There is no existential crisis, no search for meaning or purpose, there is only the inevitable suffering of servitude. There is security and predictability in that.
