No, I'm not going to talk about fishing.
Perspective exists in two different dimensions: 1) our ability to consider something against the broader contexts and 2) our ability to consider something against a lot of other individual somethings.
Healthy perspective results from our careful consideration of something - an event, a product, a process, a person - both against the "grand scheme" and many individual others. It's sort of macro and micro at the same time.
Unhealthy perspective results when we choose NOT to look at things from as many angles as possible. Myopic viewpoints always miss a lot of important data.
Disciplined minds insist that the embrace of healthy perspective prevails.
