Investing in stocks are like investing in supplements or any business. I saw Starbucks at 11 dollars a share a few years ago and I felt the need to buy it. It looked undervalued to me so I bought it. There is luck involved with any stock of course... If you don't run the company there will always be a risk. I like that you are trying to think for your future, I just think this is the wrong move.
Glad.... if you weren't going to invest in Silver what would you invest it in? Something more simple like some sort of tool that you can buy to help you do work would make more sense to me.
