It's the process of making money and reinvest make money and reinvest.
If you made just some lucky 10x profit but you can't keep up your stradegy for the long term then you don't build any wealth.
That is a pretty good point, everybody can get lucky and make a nice profit either in gambling or in trading. As long as this one-time profit is not in the millions, then this won't make us rich and it comes down to what we doing with the money after. Becoming wealthy is not a process that finishes in a few weeks, this takes years and a lot of dedication to make it work. My old boss always said that if you want to achieve financial independence then look at the journey as a marathon, not a sprint. Being lucky helps of course a lot in our efforts to accumulate money, but if we don't have a plan and the tools to secure this money for the future, then we are going to lose it mostly likely again. Reinvesting any future gains is the key to building a successful portfolio that keeps growing over time. We shouldn't be only relying on the short or medium gains in our investments, and instead build a long term investment plan.
You both make good and valid points. Just because an individual was able to get a good sum of money, may it be from luck (like winning the lottery) or through hard work (like business or work), it will take more than just that event to earn actual wealth. Let's make it simple. If an individual was able to their hands on half a million dollars then immediately spent it by buying a house and lot, cars, luxury things, and then gave some away to their family and friends, add in the taxes and what will be left? Soon enough that individual will then only have a good sum to pay for their needs and utility, and will soon face problems regarding payments for the house and cars' maintenance. Instead, if that individual made a plan and spent only what was needed, used a good percentage of that money to start a business or investment, then at least the money will make profit and will continuously give them income, possibly gaining wealth in a few years.
