Make investments in yourself to start. In your spare time learn a marketable job skill like plumber or electrician so you can receive a better rate of pay. Once you have some extra income beyond what you need for basic food, clothing, shelter, buy assets like stocks and bonds that pay you for owning them. That is how you will increase your wealth and financial security. Stick with mutual funds from the Vanguard Group like Total Stock Market Index.
I'm actually going to a local college soon to learn machining to build and repair firearms. Should be done in about 1.5 years if all goes according to plan.
I'm going to research this whole mutual funds thing. I've heard those words tossed around before but I don't really know what they are.
