I'm all for finding ways to motivate yourself, but there's no need to spend this much time on interview prep. Google is a great company to work for, but there are many other good ones out there, and any application process is always a roll of the dice. Google turns away plenty of extremely qualified people (as do every other large tech company) and they also occasionally hire some incompetent ones. Pinning your hopes on a single company is a recipe for disappointment.
