In the past, the salaries of working people provided them with the opportunity to build their future. Most salaries today are just enough to live on until the next salary and not enough to do anything additional. The biggest problem of employees today is their inability to invest for the future.
It is necessary to take steps to start a new business or generate additional income. If a fixed salary is not enough, it is necessary to look for ways to invest for the future. Investing is one of the biggest things you can do for the future.
Salaries have been stagnant for decades now, so anyone looking into an early retirement needs to prioritize such a goal and if possible decrease their spending as much as possible, because even if it makes sense to try to increase our income by getting a second job or starting our own business.
