The truth behind what happens with us is that we cannot decide what is going to happen. It actually depend on our actions and the actions of others with respect to us.
But the Quote which I follow in accordance to it is :
We cannot decide what happens with us but we can decide how we are going to respond to it.
Don't cry about the situations, try to get the most out of them. Learn from your past apply it in present and see improvement in the future.
