Robert Herrick said this quote

To the Virgins, To Make much of TimeGather ye rose-buds while ye may,Old Time is still a-flying;And this same flower that smiles today, Tomorrow will be dying.The glorious lamp of heaven, the sun, The higher he’s a-getting,The sooner will his race be run, And nearer he is to setting.That age is best which is the first, When youth and blood are warmer;But being spent, the worse, and worst Times still succeed the former.Then be not coy, but use your time, And while you may, go marry;For having lost but once your prime, You may for ever tarry.
