Is inflation going to hit hard?

Ok, by now, you should know that commodities have had a huge rally over the past two years. The question is, will it be passed on to the consumers to the same extent? If so, is there a way to retain purchasing power from here on out. Of course, you would be retaining your purchasing power if you had been buying gold and silver. Heck, any commodity would have done. But now what? What should you do with your pay check? I’m trying to figure this out. I want to retain my purchasing power.  I don’t want to buy more gold–I think I have more than enough exposure.
