In Rich Dad book they talk about 4 ways of making money. Working for other person, which I am doing now, working for yourself (freelancer), creating a company (like Elon Musk), and investing (like Warren buffet).
To me creating a company is way too much stress and time consuming, as I am focused on my family thats a no.
I have worked as a freelancer and its ok, I would say its a very good way to make money for people whose skills can be almost directly used by the final client. Like
@Luca skill with dogs. It may be also nice way to get extra money out of a hobby and test ideas. I could (as an example) paint some miniatures for people, try to sell some art or become a personal teacher at some online platform. Most people in this category lack business skills to some degree. For those of them I recomend this book:
The Personal MBA - Josh Kaufman
I am currently working for a company as the boss of a small specialists risk analisys team, and its very nice to just direct the team. I have a good health insurance, I can forget about work after my leaving time and my weekends are free. I can also take vacations. So its nice now. But It was difficult before getting to my current possition. And social soft skills are very much needed, so a lot of masking. I would say this is also worth to try. To me the trick has been to consider every work as something just temporal, so I would not fall into the consumist trap. So I always try to save something.
Finally investing is what you do with savings and to some point it is as important (or even more) than working skills. The first years, saving a bit more and investing well may be just the 1% of your Equity. Over the years will steadily catch up with your earnings, and by the end of your working life it must be your main earnings source and most of your Equity should have come from this source. I know a lot of people who have spent 5 to 10 years into learning about some stuff to earn money but less than a week to learn how to save and invest properly. This is a very big mistake.
Best of luck.
