Unexpected happiness (or grief)?

Grey's anatomy quote

"We all think we’re going to be great and we feel a little bit robbed when our expectations aren’t met. But sometimes expectations sell us short. Sometimes the expected simply pales in comparison to the unexpected. You got to wonder why we cling to our expectations, because the expected is just what keeps us steady. Standing. Still, the expected’s just the beginning, the unexpected is what changes our lives"

I had to stop for a moment to think on this quote. I, who was in the middle of researching about 'global warming', accidentally found a blog with this quote in it.

I had to meditate these words: what are these words supposed to mean for me?

Having your wish come true, getting a present you have been expecting, or receiving a reward you have been thinking of is a happy thing that can cheer up your life. But, how about if you are greeted by the unexpected? Will you pass by and keep on going? Will you run away? Or will you be discouraged and stop?

Whatever you do (or have done), remember that these unexpected things coming to greet you are about to change your life, mostly in a good way. At least, this happens to me.
