We all doing something currently we might have job side business or actual circle of people in some field.
So what Ever you do just do it better and that's how you get wealth.
Stop looking for things what you don't do it but improve those things what you allready doing it Im sure many of you are involved in crypto so get better with crypto.
What Ever you do it now just get better on this you don't need to search for things what to start just improve things what you have now.
I understand you are trying to motivate people to put effort in whatever they do in order to increase their wealth but your last part I bold is never a good way to increase wealth. Even if what you are doing is giving you some reasonable profits, you need other alternatives sources just in case. For example, an employee while working for his employer must be searching for other alternatives to become independent and manage his own wealth.
You don't put more effort to enrich someone else till eternity, you also need to search for new things to help better yourself. Crypto is one thing that needs a back up plan due to market fluctuation and it doesn't always favor consistently. While you are putting effort in what you do, it is advisable you have alternative source to maximize your wealth creation.
