To MrsK,
My story is similar (DoD for 33+ years, FIRE at 58 years old "too young"). But now I go to the gym more, stay up later, take naps whenever I need one, read everything I get my hands on, practice guitar, take courses, home renovations, car repair, attend to my investments, etc.... I really don't know how I had time to work!! When I do see my old work mates who have to work for many more years, they tell me they "hate" me. (I love it!)
