The linear experience of time allows us to logically understand our life: where we came from and where we are going. This allows us to make sense of our experience, and set expectations. When our expectations are too high we find much disappointment; when they are too low, we sabotage our own growth. We should work hard to find the balance in this so that what happens in the future in pretty much what we expect. This sort of time we experience in short duration. Today I have one story about who I am and tomorrow that story has changed, even just a little bit. The experience of time on this level is not absolute truth, but it should be more or less in accord with reality. This works thru our short term. This is one way of knowing the self.
