What would you be doing with your life if you had the choice to start over? Would you make changes? Are you in the career you wanted from the start?
For me, I'd go back and study interior design so I can make your house look like the above photo. Mike has a thing for cooking, so I'm pretty sure culinary studies would be in his back to the future plans. There's a million other things that I really love and would like to have seriously focused on before I just settled in on the cliched college, graduation, 9-5 routine.
