Should and must are very dependent on what you want to do with your life and where you want it to go. For me, I SHOULD go to school every single day for the entire week. But I MUST, go to my college, talk to the head of engineering, go flying for a few hours. We need to get away from should and go with our must, but going with must sometimes means doing what others say is wrong. But I say follow your dreams and your heart. And in the end everything will work out.
