I think about retirement every day. I'm 10 years away from a feasible early retirement. I also know I get bored easily and more than a few days sitting around the house and I get in a major funk. Retirement planning (dreaming) for me is as much about what I will do as how I will pay for it. My kids laugh because I have a list of a 100 jobs I'll do in retirement, some pay, some volunteer. I have more hobbies than time and I love learning knew things. I love photography but am honest enough with myself that I couldn't live in a National Park and shoot photos all day every day without getting bored. But I could take a job in a park for the activity and access rather than the money - or be a campground host. I also have enough hobbies I can rotate them as we travel. I plan on volunteering with a disaster relief organization to still help others in an active way.
It's about knowing yourself. If your business gives you the flexibility to have 3.5 day weeks and 6 weeks travel that might be the answer. I will be 50-60 hour weeks until I retire with a couple more deployments. As much as I enjoy my job, I look forward to freedom from the grind and ability to spend time with family.
