I made a life-defining decision 4 years ago, and it still haunts me today on a daily basis because the choice I ended up making didn't turn out the way I wanted it to. (i.e., chose to study at a college in a major that didn't really suit me, and now it is appearing to steer the course of my life...I've tried changing this course, and likely will continue to do so until I am satisfied. but in the mean time, I keep feeling regret day in and day out...)
Anyone else here have regretted a life-defining choice, and how did you overcome it (if you were able to?)
