One does not just enter the Shabbat; one prepares all week for
the arrival of Shabbat, one prepares more in earnest beginning the
fourth day of the week, and one prepares with utmost mindfulness on
the day immediately prior to Shabbat. If we want to gain the most out
of Shabbat, it requires - and deserves - our careful, proactive preparation
and forethought. (from Conclusion)
