Christmas tree leadership (Tannenbaum/Schmidt Continuum)

O Christmas tree, O Christmas tree,
How lovely are thy branches!

For some reason, this little portion of the third stanza is all I seem to remember of the song, despite hearing it repeatedly from late October through mid-January for decades.  It's an ode to the beautiful Christmas tree, and has been recorded with many different lyrics over the past 50 years.

Practical business advice.

To save time is to lengthen life.  Every businessman, every accountant, and every student who employs the shortest and best methods to arrive at results, is doing his work with satisfaction and profit.
