If flipping burgers isn't for you, I received a great piece of advice once, take some time and work for a used car dealership for a few months. Point being everyone should learn how to sell, how to be a salesman, you can be the most technical person in the room but without the ability to "sell" people on your product or articulate what makes it worth while, you are missing a key element. And face it, if you can be successful selling used cars (or cars in general, in this economy) you'll have a very practical skillset.
