Most people tend to underestimate themselves excessively. Many say, “Humility is the virtue,” perhaps influenced by social environment and education, but it’s more about recognizing mistakes and limitations than about one’s own potential. That is, self-judgment based on experience. Of course, there will be mistakes and limitations in the future that we haven’t yet encountered, but the possibilities and achievements will be just as numerous. If we assume the odds are about equal, then we shouldn’t need to underrate ourselves. Excessive self-confidence or showiness is a problem, but so is underconfidence. Too much or too little is called arrogance. In Christianity, it’s considered “sin.” - Joseph’s “just my thoughts”
In business, capital means business funds. A successful entrepreneur often says, "I started my business without any capital". It's partly true, but it's a lie. The entrepreneur just said that capital means only cash. However, all kinds of businesses need to be fundamentally business funds in any even not cash. The entrepreneur didn't count the founder's labor cost. No inputs, no outcomes. The uncounted labor costs are called "alternative costs" or "opportunity costs". This comes from comparative advantage. If the entrepreneur doesn't accept the uncounted labor cost as a debt, the entrepreneur is equivalent to losing the profit due to opportunity costs. Please always remember this. There is no free lunch in this world. - Joseph’s “just my thoughts”
