> NOTE: I have no idea why I thought I’d want to retire so late…

Yet, this article seems to skip the question of why one would want to retire early in the first place. When you're 30 or 40, not having to work a day for the rest of your life will likely seem attractive for a week or two and then get incredibly boring. Unless you want to do (near)full-time volunteer work until a real retirement age, but that's not the vibe I get from the blog.

I'd like to propose an alternative: save less than you were originally planning, spend more money on your life now (e.g. travel to a place you've always wanted to see or support a charity close to your heart) and work for longer. I haven't reached this age so I cannot comment from first hand experience but I believe most people would be happier this way.
