I did that, medical leave for 6 months... the first month was great, after a while, without the rhythm of work, I fell into a mess. I didn't take care of my personal hygiene, laundry piled up, dishes were constantly in the sink... if everyday is a Saturday then there was always time to do it 'later'.
I got a preview of what I thought my dream retirement would be and it turned out to be a nightmare. It was so bad, I went back to school.
Now I make 2x what I used to 5 years ago and I have a better idea of what I actually want for myself.
I think it's totally normal to want to be responsibility free, but the responsibilities that we have often are what push in a direction in life.
Had the opposite effect on me. I was so happy not working. Went on a hike or bike ride daily, read 10000000% more than I would normally, got more exercise, ate a lot healthier/better, more time for friends/family/pets and new relationships, and learned some new skills which I used to get a job in a field I now hate.
