Sometimes i think it's better to think of the worst. Cos things will always be better than that, somehow, in one way or another. What can be worst than worst right? Worst is the ultimate, an end to a spectrum of the extreme.
So, sometimes, it's best to give up. And think of the worst.
Also, when you throw the towel in, completely or half-heartedly, hope will dissipate. And without hope, there will be no disappointment.
We will then, be happier.
