All will be gay when noontide wakes anew,
The buttercups, the little children's dower. [ Robert Browning ]

When we mean to build,
We first survey the plot, then draw the model;
And when we see the figure of the house,
Then must we rate the cost of the erection;
Which if we find outweighs ability.
What do we then, but draw anew the model
In fewer offices; or, at least, desist
To build at all? [ William Shakespeare ]

If the world does improve on the whole, yet youth must always begin anew, and go through the stages of culture from the beginning. [ Goethe ]

Life is as a slate where all our sins are written: from time to time we rub the sponge of repentance over it, in order to begin to sin anew.
