Determining when not to overestimate and when not to underestimate is a crucial skill that is not easily acquired. But it's unspeakably important to be able to know when not to underestimate, for example, another person's affections towards you; but then also when not to overestimate the same thing. If only we could all have radar that could tune into these two measures of living, we'd name it something like "humameter" or "give-a-shit-o-meter." Either way, unnamed or named, I've learned that this is among the most important skills accomplishable by mankind. Insecurities should not be allowed to dictate how we determine the amount of value another person has placed on us; fears should not be let in to tell us how much or how little of worth we have in someone else's eyes.
