This is written in a humble tone and does a good job of addressing the difference between reality and the message we are sold as high school and college students that getting a degree in any field guarantees you a career, and that you will love your job. It is impossible to know which field will ultimately pan out at the age of 18, and those you trust (professors, teachers) will mislead you, albeit unintentionally. I think the other message is that you shouldn't wait for something big to happen to start enjoying life.
