Truly I say unto you, if I had one nickel for every time a thing I thought would take two hours took two days (or two weeks), I would have several dollars. Tuning oneself to a standstill happens all too often. If you don’t have to be anywhere, no problem. But I strongly advise against any unnecessary moto-tampering to your primary transportation the day before the big Postal Exam, the morning of your Bat Mitzvah, or on any day when the zombie apocalypse is likely to occur. Having backup transpo also means you don’t have to rush the job, which can result in all sorts of misadventures.
