Fine, if you have a lot of money to waste on your space program and aren't concerned about astronaut life.

Take the road less traveled.

Sometimes a road is less traveled because it leads through a dangerous area of town where people try to open your car windows with hooks.

Nothing is as important as passion.

I would say "competence" actually might be slightly more important than passion. I understand that it is important to feel strongly about things, but give me a competent dentist over a passionate dentist any day, if only because something about the phrase "passionate dentist" is deeply unnerving.

Do one thing every day that scares you.

I feel as though this is how people wind up in committed long-term relationships with Marilyn Manson.

Don't be afraid of rejection.

This is good advice, unless you're a transplanted kidney.

Stop to smell the roses.

Honestly, most roses smell the same. You smell one rose, you're basically set. But "stop to smell at least one rose in the course of your life" doesn't have quite the same ring to it.

Follow your passion, wherever it takes you, no matter the obstacles!

In some states, following your passion is considered stalking, especially if you are following your passion for a number of blocks in a car with the headlights off and the obstacles include "a restraining order."

Do what you love and it won't feel like work.

This is true. In most cases, it won't feel like work because it is not, in fact, work. For instance, if what you love is sitting on your couch all day eating found cereals and watching back episodes of America's Most Wanted, the correct term for this is "being unemployed."
