Expectations is the worst thing in the world. Expecting something from anything or anybody can put you in so much trouble that you can't imagine. So looking at what you are expecting and then looking at the other options is very important, what if does not happen as expected? What if the things don't go in your favor?
I have put myself in a lot of trouble always because of only expecting and not looking at the other side of the picture and that is what i have learnt now and this is my advice to everybody to look at the negative side of the picture first and that is whats going to make your decision even stronger.
