It is fairly obvious, but there are people out there that have written 200 pages self-help books and made a fortune out of them by simply stating this simple fact of life: "you can invest your savings. If you ain´t got any, you ain´t gonna invest". (I admit you could argue that you can borrow but still nobody ain´t lending ya if you ain´t gonna givvet baksh).

The basic concepts that will save you a 15 bucks book:

- you invest so that your money works for you. Even if you cannot drop your job, you can still live a bit better with extra income.
- Investing is sacrificing something today to get something tomorrow. This is just a definition. You save x today because you want 2x tomorrow or in year or whenever.
- The first step to invest is saving part of your income. No savings, no future.
- If you have credits unpaid (other than mortgages or other asset backed credits), you pay those first because they charge you a lot.

And from here we could start speaking on how are you going to save regularly, if it is going to be 10% of your income, or 5% or 50%, how are you going to learn about investing, etc...
