I read somewhere that this Universe is made as a mirror.
If you want it to smile at you, you need only to smile at it.
The trick is that you should smile at it first. 
Strangely enough I remember this thought coming to my mind when I as 16 years old. Very interesting!
The other thing is that people see in you the problems they have to resolve in themselves.
Also I remember when I was pregnant I was thinking that half the young women in my town are pregnant too. That was not true, of course, but because I was thinking about my pregnancy all the time, that was what I was seeing outside all the time.
So it works both ways - for the negative and for the positive stuff.
The best way is to focus on the positive side ...
.... or that's how we will hide from the problems? That's the question I ask myself now.

Hate to be a pedant but if it's a mirror it will always appear to smile after you smile, due to the length of time for the light of your smile to reach it and then be reflected back.... If it smiled before you smiled it must be relating to an earlier smile which you have since forgotten about.
