Someone in your social circle has a chip on their shoulder, and they feel like they deserve something that you have. It's reality check time -- you earned what you have fair and square, so do not go on the guilt trip they have all planned out for you! If you take their jealousy seriously, you'll be validating their claims. Tell them you are sorry they feel that way, but they are completely capable of getting to where you are, and you are ready to help them.
