Well, this is an insta-classic.

U.S. Navy admiral and University of Texas, Austin, alumnus William H. McRaven returned to his alma mater last week to give seniors 10 lessons from basic SEAL training when he spoke at the school’s commencement.

McRaven, the commander of the U.S. Special Operations Command who organized the raid that killed Osama bin Laden, stressed the importance of making your bed every morning, taking on obstacles headfirst, and realizing that it’s OK to be a “sugar cookie.”

All of his lessons were supported by personal stories from McRaven’s many years as a Navy SEAL.  You need to watch the 20 minute video to grasp the magnitude of his words, but here’s the list of his 10 lessons.
