How much of a life changing experience is it?

I've heard people often say they have had a life changing experience. An experience so profound that it redefines your very definition of life itself. An experience they say, that makes you realize:

How much more there is to live for.
How much less you’ve accomplished in life.
How much people you hardly knew cared for you.
How much more people you intimately knew cared for you.
How much less you should’ve cared about worthless things.

How much more you should’ve cared about the worthwhile ones.

How much you miss some people.
How much you were missed.
How much less some people think about you.
How much less you think about them.
How much things could have gone wrong.
How much things have gone right.
How much less time you got in this world.
How much of it you wasted doing nothing.

How much you wished you had done the things that you've always wanted to,

With those few special loved ones that you've always wanted to be with.

How much you wish you haven’t done the things that you have,
To the ones who didn’t matter.
How much close you brought your own destruction,
Much less others, by your own stupidity.
How much closure making peace with your dear ones can bring,
More so with yourself.
How much you wished you never had to experience this.
How much you wish you had realized it all without one.

I too have had such an experience and those were 24 lines of my realization.
