Good night, good night! Parting is such sweet sorrow, that I shall say good night till it be morrow. William Shakespeare
We can easily manage if we will only take, each day, the burden appointed to it. But the load will be too heavy for us if we carry yesterday's burden over again today, and then add the burden of the morrow before we are required to bear it. John Newton
Ah, Hope! what would life be, stripped of thy encouraging smiles, that teach us to look behind the dark clouds of today, for the golden beams that are to gild the morrow. Susanna Moodie
Man's yesterday may never be like his morrow; Nought may endure but Mutability. Percy Bysshe Shelley
A fresh mind keeps the body fresh. Take in the ideas of the day, drain off those of yesterday. As to the morrow, time enough to consider it when it becomes today. Edward G. Bulwer-Lytton
