Your plans will change dramatically. Be prepared. Wear comfortable shoes.
We all judge books by their covers. It's inevitable and it's very human. What really matters is that you give the contents of the book a fair chance. You've judged someone by their cover recently, and now you're beginning to wonder if it was premature. Was it the right judgement? This is a good time to take a peek under the cover, turn a few pages, and see if there was any substance to your judgement.
A wonderful career is not enough to give you a wonderful life. It won't automatically give your life meaning. Meaning comes from a range of things; not just your work. Other parts of your life are important; don't neglect them.
