I'm not sure why students have this idea that once you're "done" that life becomes suddenly awesome. I finished residency this year and only became board certified earlier this week and I'm in my 30s. I suddenly make a lot more money but it's not as if my quality of life shot up instantly. I took a cushy job (and probably sacrificed some income as a result) but others in my residency class are working A LOT harder as attendings now than they did as senior residents.
By the same token, it's not like life before now was all drudgery. Having to be a glorified ass-kisser MS3 was probably the worst year of my life, but I had a lot of fun outside of school during that time. I got to go to theater shows, I had MLS season tickets, I played on my school's inter-grad school soccer team that played against other city med schools for a season, and I went out just about every weekend. In residency I lived in one of the trendiest neighborhoods in the country, met Ms. Ox, traveled a lot, ran a few marathons, went to a ton of concerts, and still somehow saved 8% of my income for retirement.
