While you have a future do not live too much in contemplation of your past: unless you are content to walk backward the mirror is a poor guide.
It is perfectly true, as philosophers say, that life must be understood backwards. But they forget the other proposition, that it must be lived forwards.
If we live out of our memory, we're tied to the past and to that which is finite. When we live out of our imagination, we're tied to that which is infinite.
Ever since I made tomorrow my favorite day, I've been uncomfortable looking back.
I think it is better for all people to live on, to look forward to the next stage (after death), as if he had to spend centuries, then he lives properly... looking forward to the great adventure ahead, then he lives!
I'm not a nostalgic person: I never look back; I always forget.
