Gather the flowers, but spare the buds. - Andrew Marvell

Like the vain curlings of the watery maze,
Which in smooth streams a sinking weight does raise,
So Man, declining always, disappears
In the weak circles of increasing years;
And his short tumults of themselves compose,
While flowing Time above his head does close.

The same arts that did gain
A power, must it maintain.

Now therefore while the youthful hue Sits on thy skin like morning dew, And while thy willing soul transpires At every pore with instant fires, Now let us sport us while we may, And now, like amorous birds of prey, Rather at once our time devour Than languish in his slow-chapped power.
