Same boat as you, OP. Second year out of undergrad, working in a lab, and planning on retaking the MCAT.
Some of my friends can be asshats about where I am in life and where I want to be. But at the same time, I look at it as a way to enjoy life while I'm young, dumb, and full of fun.
Think of it this way: a lot of your peers will have not had a full-time job or really experience the real world until they're 26 and being treat like crap as the intern. The bombshell being dropped on them is a bigger whammy than graduating college and picking up a lab job as a tech and learning to pay rent, bills, etc. But, only working 40 hours/week leaves me a lot of time to pursue interests I would have had to put on the back burner until I'm in my mid-30's. And my interests are through sports and working out. I'm taking advantage of my youth to be able to work hard, be in the gym for a few hours, study, and still have the energy to go out with friends to build long-lasting relationships. Oh, and I got to travel around the country on my own dime with friends I wouldn't have made in medical school.
Last year, I went to 3 different music festivals on the east and west coast and had the time of my life, as a 23-year old single man. THAT'S what life, I believe, is all about. Doing what you want (if you put the work into it.)
So who gives a flying f**k if we wait a few years before we dedicate our lives to medicine? Medical schools aren't going anywhere. The MCAT will always be tested at around the same times each year. The post-bacc I want to attend will always be there as well. Might as well make the most of our unique situation.
