What the actual fuck are you talking about here? Not only are you poor, you are an idiot too. Most of the wealthy people, especially in the most modern generation have gotten all their wealth primarily due to luck. Most of them are complete idiots, and here you talk about "wisdom". Not even the top billionaires display any sign of any kind of life or business wisdom whatsoever. They are often making the most basic errors imaginable, they can't even hold a marriage together and here you are talking about some "wisdom".

If you started analyzing the list of rich people, you would see that almost all of them were the result of circumstance, connections or family wealth.
The easiest way, IMO, is upskilling. Adding value to yourself by increasing your expertise, through training and certification, could help you earn more. It's definitely something that could be useful in the long run, and skills would always be with you. This would be about long-term investing for yourself.
This does not in any way guarantee that one will reach any considerable wealth. In fact, if what one does not know what they are doing they will be exploited. They will be given more work and responsibilities without actually getting the pay that should be deserved. You make it sound too easy, whereas in reality each step of that process is considerably difficult. First to actually learn the skills, then to find a place that will value them, and finally to successfully utilize them in the practical sphere.
Nothing is instant; everything requires effort. Wealth does not come by itself while you are lying down, but because of effort and belief in doing it.
Rich kid: Yes, I have invested considerable effort to inherit $100m from my parents. If you do not work hard like me, you won't inherit money like this. Are you actually this retarded or did you write whatever came to your mind just to shitpost?
