Hope and Despair...

I believe that feeling of hope you experience is masking the underlying despair. Despair inflicted by being at the end of the rope, rooted in the feeling of failure. Keep in mind, you shall feel happy that you were able to squeeze out microscopic amounts of toothpaste, or chew out the last nanoliter of flavor from a gum you were chewing for the past 4 long hours. But the next day, when you try squeezing more, you shall not be greeted by the sweet reward. That gum you were chewing for the past 4 hours will make your mouth dry and leave you hungry. So at the cost of sounding pessimistic, although borderline pragmatic, I would say, spit out that gum while you are enjoying it. Get a new toothpaste while your teeth are still clean. Don't let hope show you fancy dreams of wonderland. Instead be ready for the worst and make necessary arrangements for the future.
That reminds me of the classic battle of hope and despair, Angels and Demons, Dan Brown.
