Boast not thyself of to morrow
Prov 27:1 (KJV)
The only preparation for the morrow is the
right use of to-day. The stone in the hands of the builder must be put in its
place and fitted to receive another. The morrow comes for naught, if to-day is
not heeded. Neglect not the call that comes to thee this day, for such neglect
is nothing else than boasting thyself of to-morrow. –G. Bowen
