The 2 of Pentacles is an assignment number card, and the assignment here is to maintain a happy and relaxed attitude during a wait for results of what you started.
You might be able to do some preliminary work while you wait. Try to relax a bit as well.
You've started something that now practically requires you to wait a bit for results to come in. This gives you the chance to relax, and to do some final polishing as well.
You don't actually have to wait for results right now, you can proceed with your efforts, perhaps from a different angle.
