Big money is usually earned in three to five years; if you have it, you have it, and if you don't, you don't. Most of the people around me are like this. It's a very foolish thought: to open a store or a company, hoping to run it for a lifetime and support yourself for life.
This is a very dangerous way of thinking.
The reality is: you must save up your living expenses for the next five years during three years of favorable conditions, then sell the business at its peak, and in the following days, drink tea, chat, and explore opportunities,
looking for the next trend. Make sure not to hold on too tightly; the outcome often leads to losing back the profits from those three years, ending up heavily in debt.
