The best way to be appreciative for your life is to live it; don't die for any other reason but love. Dreams are what guide us, art is what defines us, math is makes it all possible, and love is what lights our way.
That which is possible is only the seedbed for that which is impossible. And therefore, if we neglect to plant liberally we might live lives full of the possible, but we will never hold the harvest of the impossible.
