But other than that, the best advice I have is to figure out exactly what you want answers to!
If you want to know things about a job situation, then pick a card for each thing you want to know. Example: Boss, Postition, Raise, What can I do better, etc.
You get the idea. I'm sure after a few tries that you'll get the hang of it and really enjoy creating and using (and sharing) your own spreads!
