Thank you for your advice.
I must say you are right about *everything* that you pointed out. I think the key fact that I will take away as the most valuable is:

Make sure your brain fully connects...
I don't think my brain has fully connected with the thought of possible failure in the absence of good discipline in preparation. I will work on that, starting...now.
And for those of the readers that are looking for other pieces of the solution to this problem, I dare recommend a talk I watched online. It is about time management and is given by Randy Pausch - a professor of computer science from Carnegie Mellon.
