I would have started programming earlier. It's a lot of fun and I'm really good at it.

I also would have gotten more involved with campus life at school before my final year in graduate school. It was a lot of fun and I made several good friends, but I wonder what I missed would have happened if I had done so earlier.

Don't get me wrong, I am very happy where my life is heading. How many people have a thesis on machine learning and could be a part of advancing the field in a meaningful way? You can't change the past, so take hold and shape your future!
