I have a smooth black rock I picked up on a beach years ago. It is almost always in my pocket. When I am going through an extra rough time, I have it in my hand for comfort and grounding.

I lost a rock I used years ago, then picked out a new one. I had asked a therapist about all this and his reply was to do what works for me. I think that is great advice.

You can get a new pencil, have fun even looking over all the various options at a store. You could decide that the new pencil represents something new unfolding, success and healthy evolution.
