Don't work for fools. It's not worth it. Getting paid less to work for people you like and believe in is much better for you (and your career) in the long run.
You're going to fall down, but the world doesn't care how many times you fall down, as long as it's one fewer than the numbers of times you get back up.
You cannot continue to succeed in the world or have a fulfilling life in the world unless you choose to use your life in the service somehow to others and give back what you have been given. That's how you keep it. That's how you get it. That's how you grow it.
Because as tough as things have been, I am convinced you are tougher. I've seen your passion and I've seen your service... I've seen a generation eager, impatient even, to step into the rushing waters of history and change its course.
