Time can come and bite you in the butt. I thunk that I am in this same position now. I m working late and this is very stressful. I think I can handle it but these years are hard and interesting. The thing that keeps me going is that I know I will be one soon. it is a good mindset to have when working. if you know that you will be done soon and it will be over, it makes work very easy. Stress teaches you to work hard and pushes you. I think that you play your best phased. It can make you want it more. I love it.
