for the most number of jobs in the world. People spend their lifetimes dealing with these things. People write books on these. There's countless theories, laws, algorithms, languages, programming languages and tools to solve, counter, lessen, or soften their blows.
This question is: How does a problem arise?
I will be succinct and write points:
- It was not anticipated.
- It was anticipated but unavoidable.
- You were just being careless.
- You just didn't care. In this case, the "problem" might not be labelled one, at least by yourself.
- The problem was a benefit until it became a disadvantage and turned into a problem, which turns into point number 1 again.
