Most of the time to become rich is not just a matter of luck, but most of it is the result of hard work and smart work. Therefore, there are many successful people who usually work harder than most people. On the other hand, whether it's investment or real work, it's basically the same, it requires a hard process, even by combining the two, real business and investment, both require a lot of effort.
In my opinion, to be able to make someone have a lot of wealth, of course they have to work hard and not easily give up on what they are doing and it is absolutely impossible for someone to get wealth easily without working hard and if only they could get this wealth, of course they would have done it with an illegal method and even that will not last long because what they are doing violates existing rules.
You are right, in various fields of work it certainly requires a process and we must have a good understanding of what we are doing to be able to carry it out well and if we experience problems in what we are doing of course we must be able to solve it well and if you are able to carry it out real business and also investment, of course this will easily make you rich.
