Correct on all counts -- nothing tying me down, and my rainy day fund can keep me fed, clothed, and sheltered for years.
I actually get a decent amount of exercise -- minimum 40 minutes per day, I'd estimate. It certainly has plenty of benefits, but the energy seems to evaporate once I get down in front of my keyboard again.
I definitely can go out and change things, but I think my mindset is holding me back. It's almost like I would be doing with the expectation that this would "fix" me, and that anything short of that would be a waste.
Yes, yes, I know I'll regret the things I didn't do. But I fear that I'm setting myself up for failure this way with unrealistic expectations.
