Time.. For today it one of hardest thing to undestanding. Usually people imagine this substance like a river — you can’t go in and go out into the same water. The Science wants to represent time as on of dimensions — the fourth after Height, and maybe it has sense.
We never met any person from past or future. In our minds we can say that time is never been — it only moment of now we can feel and see. But in religion, for example, have place appears of saints, that are lived many time ago. It gives us a idea of Eternal life — the life that haven’t a time.
But our reality is river of time, and our lives are full changes and unstability because of that. And if we have understand that fact, we can make a wonderful thing — write a letter from ourselves to us in the future. But what can we say? What warnings we will tell and how questions we will ask to the person, that we don’t even know for now?
In science fiction there is a separate genre — futurology. Writers of this genre try to look to the near and depp future, and paint to a people a picture of what future peolple will do and what things they will use. There are many thing that last writers predicted correctly, for example video callings or space research, but in some things they are made very optimistic assumptions, but in fact we didn’t do what they are expected from us, or didn’t use the things rightly — accordingly to their waitings. For example we use powerfull computers to look at cats and play games like Flappy or Angry bird.

But one of most usefull and right thing we can do — ask to future ourselves the questions:
1. Are you wasted your time for rightfull things?
2. Are you still have hope to the future and do maximal efforts for future targets?
3. Did you do right things that you want to do in the past?
What kind of questions or advices would you ask or tell?
