worth it

Now that our monthly amortization for the car is done, i am thinking on where to invest some of our money. I am afraid that i will just spend it with nonsense stuff, so i must really come up with a concrete plan of not just putting it at the bank. I have the option of getting a few stocks , but since i'm not that familiar with stock options, i might try out investing with gold or silver. I plan to call the customer service of Monex so i can inquire with the silver price . I actually got this idea from a friend who already got a few pieces of gold. She said that it's worth investing with this since the value is really going up. Silver is one metal that is on high demand now because of it's properties so that would be a great investment too.
