If you are/were like me, I want to hear your personal experiences in how you picked something to focus on and if you would do it the same way if you had to start over.
If it makes any difference, I am 21 years old majoring in CS. I have made it a point to try out CS classes in several different areas throughout my stay here. Also, I do not plan on going the PhD or large company route: I like the idea of startups.
