Confusion is all I see.

I feel lost in my calculus and my Physics. I feel there are not enough hours in the day to find out. I know I need to solve this problem, because I need these classes to complete my major. I am physically disappointed in myself and I feel my body should be able to do more. How do I fight exhaustion? I don’t know, but I must buckle down. It must be worth sacrificing all this time. I have to reach the destination; therefore I must take the journey. My passion is the greatest wish and ultimate goal.
