Hashcash I think this is a really good look at the weekness of being too focused on the numbers. Of course we can have weekness on the otherside as well, being unfocused or lack of focus.

Like so many things in life, virtue lies in the comfortable medium between two extremes. We must have strong vision and clear goals, but also be flexible to seize opportunities and maintain motivation.

Thanks for sharing, this motivated me! Steem on!
