Mary Oliver said this quote

Every springI hear the thrush singingin the glowing woodshe is only passing through.His voice is deep,then he lifts it until it seemsto fall from the sky.I am thrilled.I am grateful.Then, by the end of morning,he's gone, nothing but silenceout of the treewhere he rested for a night.And this I find acceptable.Not enough is a poor life.But too much is, well, too much.Imagine Verdi or Mahlerevery day, all day.It would exhaust anyone.
