How to manage my money - no matter how much you make you can put your money to work for you to create wealth. Start by saving a very minimal amount, then once you have a little bit of savings, put it to work.
That’s the point of the book. It doesn’t matter how much you have. It’s how you use it. You find ways to turn 1 saved dollar into 2. Save 10% of the profit, now you have $1.1 - repeat. One of the main points is that everyone earns different amounts, but everyone ends up equally broke. Pay yourself first ;)
But put it to work in terms of investment? what if you don't have a big enough amount?
