In college, we wanted to start our own fraternity. The dean of students told me, "Michael, there will never be another fraternity added to our campus."
I had a choice at that point, accept what he said and give up or keep going for what I wanted. This video speaks to never listening to anyone else's opinion when you want something!
There will always be a reason why you can't at the same time, there will always be a reason why you can!
