Hoping for the best
They say, "hope for the best, but expect the worst, because then you won't be disappointed." But this poses as a negative construct for the mind.
You retract from the experience of disappointment, so you put yourself in a position of expecting the worst. However during this period of expecting the worst, you become consumed by a negative state of mind.
Although there remains a part of you that hopes for the best, this hope cannot be maintained if you open your heart and your mind to the possibility of a negative outcome.
Alternatively, you should simply hope for the best. And if this "best" isn't the outcome, you should face disappointment: acknowledge it and live it, then move on.
Because if we don't face disappointment, that's a part of life we'll never master.
