Credit Rating and Required Rate of Return: Suppose you and Warren Buffett borrow money from a bank. The bank will assess your credit ratings differently. Maybe the bank could offer Warren Buffett a loan without interest since it can be advertised as a bank used by the renowned investor. However, it will likely charge you interest because you have a lower credit rating and less fame than Warren Buffett. The interest rate each borrower faces, based on their creditworthiness, is called the required rate of return for creditors. Under the same conditions, the cost of poverty is much higher for the poor than for the rich. Poverty inherently involves costs. - Joseph’s “just my thoughts”
The advice to concentrate on one thing instead of trying to excel at many is valid, as it’s also challenging to master a single skill. If you neglect the other essential background abilities necessary to enhance that one skill, you will be unable to overcome your limitations. For a top-level skill to thrive, the supporting average abilities for that skill must also develop concurrently. Concentration should not be an excuse to avoid or ignore what’s important. - Joseph’s “just my thoughts”
