Affiliate Marketing Secrets

Hey, I really want to invest my 500 pounds into a business to make a profit but I don’t know much about the stock market and the ins and outs, can somebody fill me in and what to invest on and when? And any other secrets? Thank you very much guys. Daniel.

I’m 16 and I’m already going to start saving and I will be investing in the stock market again with my grandpa shortly. I work at a law firm helping my grandpa who is a lawyer, and I want to start saving and investing my money to increase my “net worth”.
I’ve read Secrets of the Millionaire Mind by T. Harv Eker and I really enjoyed it. It made a lot of sense to me, I really recommend that you read it, but anyways do any of you know of any great business books you recommend?
I already found one book called Think and Grow Rich – Napolean Hill that I might buy.
