It is often noted, ad nauseum, that once people taste a wee bit of success, they start to feel that they are demigods and anything they touch will turn into Gold.
Success often does not come in leaps and bounds, but through steady work. Yes, sometime luck turns the table, but do not think those as Midas touch.
Take the example of Anil Ambani, one of the richest businessman at that time. After the split between brothers and got lot of money and modern era business - like ICE- Infrastructure, Communication and Entertainment. He went on to establish Ultra Mega Power Station, he went on to buy internet cable companies and set up a huge infra for mobile and internet and of course the Bollywood area thanks to his actress wife- the entertainment business. All these businesses required huge amount of CASH and TIME for it to fructify. He was on steroids, borrowing left, right center to finish his projects. End of the day, he ended up in such a huge pile of debt, that he has not been able to come out till today. His brother helped to buy for a pittance, the communication part of the business and renamed it Jio.
His elder brother has refinery, which is a cash cow and generates cash, which he can slowly deploy into communication and wait it out. No need to go in for large borrowings or Ego issues to grow big quickly.
The fundamental lesson you learn from above is that taking a small debt where you have the ability to repay by sale of some of your assets is fine for a short term, but longer growth financed by debt where the outcome is not a certainty would land you in one big hole that will be difficult to come out.
Ego in business may be good, but has to be accompanied by Sanity. Ego helps you to push forward, but Sanity roots you to the ground. When the going is good, repay Debts, try to hoard cash for a rainy day and when opportunity comes you can use it. Life is a cycle. It is not that you miss one you are out, there will come a time to join the cycle. One has to wait out. This equally applies to our investments. Just because everyone is making money on a flavor, you may be tempted to join. But just check out and do not put everything into that as one day the flavor goes out you have huge debts and unable to sell. That is the most difficult situation for a businessman.
In any case, ensure that family is assured of a steady income stream not linked to any business venture to avoid creditors and govt. to come after that.
