I think your first sentence is backwards, unless you're assuming TheProwler's friend has a sexy wife (and a more balanced life than you).
Also, I found the clinical years to be less time-consuming for me. Busting my ass the first two years in similar fashion to TheProwler's friend made third year so much easier in terms of studying for shelves/Step 2. Despite what some people tend to think, a good bit of M1/M2 (more so M2) course material still ends up being high yield during M3 even on exams. Getting to M3 felt like a huge breath of fresh air for me, and I suddenly had tons more free time (with a few exceptions here and there). The momentum built up during the first two years made cruising through the clinical years (and by cruising I don't mean slacking) so much easier.
