Seneca said that, and it is true.

You have to know
where you are going in order to get there. This may
seem simplistic, but many people have no idea where
they are going in life–much less where they are
headed on the Journey of the Soul.
Yet these are things that have to be decided, not
discovered. Too many people are waiting to discover
what they should decide; to chance upon what they
should be choosing. Are you one of them?

Neale Donald Walsch
