The beginning of the week and the 3 of Pentacles shows that the learning or teaching of new skills is important. Take the time to give the benefit of your own wisdom, but at the same time make sure you are learning from the wisdom of others.
The middle of the week and the 4 of Pentacles tells you that you are holding onto something for the sake of it. No good will come of this and it is a good idea to accept when something must go.
The end of the week and Death tells us that all good things come to an end. Whatever you were holding onto, now is the time to accept that this must go. Embrace this and move on.
