I remember feeling what you felt my senior year of high school, but I didnt fail anything...or come close. I just felt generally unprepared all the time, even if I wasnt. I felt like people knew their plans before I had thought of mine. Honestly, it makes no difference I know people that have gone to horrible colleges, and now they are successfully running their own companies. My mom used to tell me something, she always said to do what you love, and to love what you do. Everything else will fall into place.
