On the solitude...

Maybe love won't let you down. All of your failures are training grounds and just as your back's turned you'll be surprised...as your solitude subsides.

W. Shakespeare 

I hold this to be the higher task for a bond between two people: that each protect the solitude of the other. 

R.M. Rilke 

Talent develops in solitude, character develops in the stream of life.

W. Goethe
