Basically it takes no money to make money. You need to use other peoples money and other peoples time. Both at the same time. Because:
- Other peoples money: if you don't have money, you don't really have another option. You could look for investors but that has so many limitations and with no past they'll barely invest in a venture.
- Other peoples time: you need to delegate as much as you can. There's only that much hours in a day.
Here is my current world view to hopefully save you some years of trial-and-error. Money can't be found on the street. It is only found in other people's pockets. Thus you need to get them give their money to you. They are happy to give it to you in exchange for solving their problems (everybody's doing that in the world - even you at home; think about shopping, cable-TV, Internet, etc; you are happy to pay because they solve your problem). Once you have a problem to solve, you need to find a solution and start executing it. People will pay you so you can start paying some employees, which generates more money in return and it goes on and on like this.
Robert Kiyosaki's materials are a great start (although it might be all fiction). Especially the "Choose to be Rich" and "The Cashflow Quadrant" series. Also the "Rick kid smart kid" or whatever it is called. Don't take the story seriously but it definitely changes your pov.
It takes no money to start. Am I right, Steve?
