I really wish I could take 6 months off from work. Not quit, just a sabbatical (unpaid). I really like what I do, the pay is good, the work matters to me, and I'd like to come back to it. But it is stressful, and I've been working since I was 15 (I have another 15+ years to go to retirement). I am TIRED. I'd envision the 6 months as:
Month 1: Sleep 10 hours a night, eat 3 large, healthy meals a day, exercise 3-4 times a week and ride my bike everywhere. Remaining time is video games, TV, and happy hour with friends. AKA "lazy bum" stage. The idea here is I've been running a sleep and health deficit for years, i need to build some credit back up.
Month 2-3, maybe 4: Travel. Go see some friends I have been neglecting across the country, stay a few days, visit, help take some things off their plates (house chores/jobs, help with projects). Let them know I'm a lousy friend because I'm constantly busy, not because I don't care. Stop in at a bunch of museums, attractions, and national parks along the way. Check off 50-75% of the things on my, "I'd like to see/do that someday" list
Month 5: Work on my own projects. 4-5 days a week in the garage spinning wrenchs with the radio on. Get the fleet to the point I'm happy with it.
Month 6: Start getting ready to go back to work. More sleep, good food, and exercise.
It would be great if we as a society could normalize time like this. Other countries do, some academics do. The 1-2 week vacations I take currently (and even that is rare) give me just enough time to get some sleep and food, and remember what it's like to feel decent and get the stress monkey off my back. Then back to the grind. It's not enough.
