I am a strong person. I lift in an attempt to become a stronger person.
My primary observation about Strength is how often is is useless.
I am a person who has a job that requires Strength - often when people are ill, they attempt to harm themselves or other people, and it is my job to keep the situation safe.
Even in this situation Strength is as much as a drawback as an advantage. It helps to be able to exert more force when opposed by someone, and to have the muscle endurance to avoid becoming fatigued against someone's struggles, but it comes with substantial risk also. I am responsible for the safety of all those involved, and cannot exert too much force or I will hurt or kill the person instead of keeping them from hurting themselves. Of all of the techniques we are taught to use to restrain people, none require being stronger then the person you're restraining.
As far as how strength applies to daily life - How many times this last week have you been asked to do something requiring more strength then you possessed. Hell, I've recently moved and even counting everything I've brought over here, smart packing and assistance of friends has obviated the need for needing extra-strength.
