I gasped and thought, every new year I say these exact words!
I don't know why but I would definitely be right to think that everyone that I know has wondered once in their life that 'past was really fast'.
Now, I think I know the reason behind it :) The reason is that we do not live in the present at all. When we see the morning sky, we don't feel its beauty anymore, because in our minds we are not watching the sky, but planning the day, or, thinking what to wear in office ( specially us girls :) ). Every moment we don't live in the present, in our minds, we are either in our past or future.
I tried it one day, that I will feel every feeling of everything that I see, that I hear, that I touch, one day. And at the end of it, I was strangely happy, for in that one day, I have lived so much that I haven't lived for a whole year may be :)
Try it! It works.
