Time travel to the future

 Hello!

I actually consider either idea, of traveling to the past or the future, to be very risky and I would be afraid to perhaps "change" the present I have. So I would take a lot of precautions about it, and I wouldn't break any rules (not like Marty McFly).  

But, by the same token, I think I'd like to travel into the future, maybe 20-25 years into the future. I would like to see how the world is doing, specifically San Antonio (my city) and Santiago, how different they are and what changes have taken place on a social level. But I would also like to know what I am doing with my life, to see if I am happy with the life I have.

By traveling to the future and seeing all these things I feel that it could make one change a lot and be able to see different things. So if there is something I don't like in my future, I would like to be able to try to reverse it and make all my efforts in the present. 

I wouldn't like to stay in the future, but I would just like to go for a while, maybe for a day, so that it's not too little time or too much, and to be able to look at everything with calm.
