Tear the head of a lion
 

This goes for gaining mass, losing fat, getting a scholarship or being great at your job - the attitude that you bring to any task will go a long way in helping you succeed. In fact, a mediocre program done with a committed, enthusiastic attitude will trump a perfect program done half-assed. So walk into the gym happy, determined and ready to tear the head off a lion and you’ll be packing on size before you know it
