Pushing the mountain

At work this morning I felt as if were pushing a mountain and this picture describes exactly how I felt.

Thinking about it I realise that I set myself up for it by asking a particular volunteer to work with a group when I know he doesn't really have the capacity to do it. I keep hoping he will learn and I try to teach him, but so far with little success. He doesn't seem to be able to take responsibility for anyone other than himself and doesn't seem to be able to organise people.

So why do I keep asking him to do it?? It doesn't help me at all!

Its as if I am creating my own mountain.
