What is the Moral (lesson) of the film ''Click'' with Adam Sandler?

Live life in the now

The lesson is that life does not stop. Make the most of the moment because you cant "rewind" "pause" or "fast forward". Dont spend all your life creating plans so that by the time you are done planning your life is over. Plan for the near future, and make your plans happen!

i miss my past 6 years:(

It's about sorting our your priorities in life, not missing the best parts, and appreciating what we do have. We should spend more time with our loved ones.
