Of course, time does not change but our perception of time passing certainly can vary. I had just recently mentioned how fast the year 2015.
At the same time, I try to think back to January of 2015, and it seems like ages and ages ago.
Here is a paraphrase (or my understanding) of what Claudia Hammond said about that very issue--
Time seems to speed up when we are busy and times seems to have slowed down when we look back on a period that was busy. So feeling that time is going by too fast is a good thing in that we can look back with all those memories of a full life.Guess I had a busy past year.
Time and memory are true artists: they remould reality nearer to the heart's desire. John Dewey
Time changes everything except something within us which is always surprised by change. Thomas Hardy
The time you enjoy wasting is not wasted time. Bertrand Russell (also attributed to John Lennon)
Time stays long enough for anyone who will use it. Leonardo DaVinci
Forever is composed of nows. Emily Dickinson
How did it get so late so soon? Dr. Suess
