The 4 of Pentacles is about holding on to what you got. The number 4 represents structure and order, and fits well with the suit's element, Earth.
Try to make a list of what you have, and what you would like to have. It'll help bring some clarity, probably.
Holding on to what you have can often result in a tense attitude. But you can hold on in a relaxed fashion as well, if you remind yourself regularly at first.
Beware that you don't become too cramped while you're trying to hold on to what you have. Try to relax and allow others their fun as well.
