hmm, i've been thinking about this stuff alot lately...
1. Although I love my undergrad and the friends I made, I wish I went to college in a different, more fun location, like Boston, NYC, or California. After this process, I realized it will only get harder to get to easily choose where you want to live...we are at the mercy of adcoms and residency program directors for a while.
2. Definitely would have went abroad. Most likely to Spain, if I had that Spanish major/minor that is now on my list of regrets. Or Australia, the students at my school loved it there. Didn't go because I was not that comfortable readjusting to a new environment all over again. Wish I had just pushed myself to do it!
3. Wish I had at least tried research before writing it off as not for me...a senior year second semester biochem lab project totally changed my mine on that one..
