The eternal now

I sometimes wonder if time is an absolute or a function of how each individual defines or perceives it. For me, when it comes to time, now is all there is. It lasts but a flash and moves on to leave the past behind it. The past is but a recollection of what just occurred. It is subject to impressions, emotions, and prior experience. As you move further away from the moment, it begins to lose its clarity. It is instantaneously replaced by the next "now." The future is what awaits but does not yet exist until the next wave of now overtakes it. You are always existing in the now. What matters is how you live your life in the now. It is a moment that will never repeat itself. That is how I see time today, and I may find that I will see it differently as it passes. When I was younger, I saw time as linear as measured by a clock. Now it looks more like a single vertical line with nothing on either side of it, the eternal now. Even the past and the future are projections of that now if I look at it this way. How do you see "now" and the time that surrounds it?
