Everyone is wise in hindsight. We value things only when its going or gone. Happy is the person who values what he has 'NOW". What is the point of crying over spilt milk?
We tend to under-value things we have now and we live in the past/future. What we need to understand is that time is 'relative'. We always tend to dwell over the past. "What if I had done thing thing, this way?". The "What if" questions create parallel fictional/imaginary possibilities in your mind. You create a castle/palace of dreams in your mind of the things and day-dream about possibilities. Whilst doing this, you shatter your present and don't give importance to people/things/situations that you presently have. You lose them and then again ponder how you could've avoided losing them. You reconstruct the events in your mind, build your dream castles which again shatter causing double grief.
However en-lightened you get, your mind is hard-wired to do this! Perhaps this is a consequence of our brains becoming too complex once we evolved from being primates. Why are children happy? They live in the present. They take things as it comes.
The same problem is repeated when one lives in the future. "What will I do ten years from now?", "What will I do in the evening today? Am I going to the Gym, If yes I have to plan accordingly. But my work commitments are also there? How will I go then? etc etc. You get the point, don't you? In the interim, something good happens around you and you do not enjoy the moment as you are lost in thoughts worrying about the past.
Noone knows what will happen in the future. Noone! God has his own plans which "super-cede" your own. Be like a child. Enjoy the present. Care about the people who care about you. Have a good nights sleep and a good diet.
Live in the present..
