Time.
Time doesn’t pass.
The passage of time is an illusion.
And life is the magician.
Because life only lets you see one day at a time.
You remember being alive yesterday, you hope you’re going to be alive tomorrow, so it feels like you are traveling one to the other but nobody’s moving anywhere!
Movies don’t really move.
They’re just pictures – lots and lots of pictures, all of them still, none of them moving, just frozen moments.
But if you experience those pictures one after the other, then everything comes alive.
Imagine if time all happened at once.
Every moment of your life laid out around you like a city.
Streets full of buildings made of days.
The day you were born, the day you die.
The day you fall in love, the day that love ends.
A whole city built from triumph and heartbreak and boredom and laughter and cutting your toenails.
It’s the best place you will ever be.
Time is a structure relative to ourselves.
Time is the space made by our lifes where we stand together, forever. 

Time
and
Relative
Dimension
in
space. 

It means life.
