The last day of any month is always a good time to bring things to a close. This spell will help to end what needs to finish so the new month might start anew. Of course, it's not without responsibility; the spell will help, but you still have to do the work! You'll need a piece of paper, a black pen or pencil, a small cardboard box (it doesn't have to be new), and some tape.

Write down what needs to be finished. This may be a relationship that has run its course, a project that is lingering, or a habit you want to get rid of. Put the paper in the box and tape it shut. As you are closing the box, say:
I close this door, to open more.
I have finished with thee, so mote it be.

Tape the box securely closed and take it out to the trash. Let the obstacles go so you can start afresh tomorrow.
