I recently read an analogy (Barbara Harris) of tasks or obligations being thought of as rocks that each of us can place into a backpack.
We pick up the rocks we think are our responsibility and put them into our backpacks.
As our pack get heavier we become resentful and angry.
This is often because, in fact, we have picked up one or more rock that really should be in someone else’s backpack.
It might be worth – like I’m doing – examining the rocks in your backpack, to see if they really belong to you.
