Let me fix that title for you...

Do whatever makes you happy (without taking reality into account) is a lie (well, not a lie, just a wee bit stupid and naive).

Like people who go to university with NO IDEA what they want to do when they get out and then whine about not having a job and a huge student loan when they graduate.

Think. Decide. Do. And take responsibility instead of looking for someone to blame for why you are where you are in life.
