Foresight is a tool we should all have in our war chests. However, many of us disregard this critical thought process. If I drink this much and drive my car, I just might crash, killing myself or someone else. If I talk about my boss behind his back to the wrong person, I could get fired for some trivial reason.
Almost everyone knows the difference between right and wrong, but do we all apply thinking with consequential logic before committing our wrongs? Probably not. The reasons are plenty, but simply put, many of us are too lazy or careless.
If it is lazy, that can be more easily fixed than that of careless. Lazy is just that, lazy. Working a little extra hard by churning the brain with logic before minor or major decisions creates a more seamless living environment for not only yourself, but everyone around you.
Careless is more difficult to fix because the person is caring less about something that requires someone to yield more care. This is a fundamental disregard for the situation or an inadequate comprehension of the dynamics of that particular situation or decision.
Usually people other than yourself are involved, assuming you have careless tendencies. Let me clarify with an example: You are on a roof reshingling with a working partner, but you are a level below him/her and this person would like to get down to your level. They ask if you could set the step ladder up so they can get down, so you do. By not holding the ladder tightly as the person descends, they fall and die.
This is a blatant example of disregarding someone else
