Making Worthy Fail List

I have committed to an impossible goal. I am scared of rejection and do not initiate invitations ever, so I set my goal to initiate 12 invitations for social occasions to 12 different people. That seems measurable, where having more/closer friends does not. The part I am struggling with is worthy fails. It is a narrow goal in some ways and I can come up with side related goals, go to an event and introduce yourself to 2 people, do a Toastmasters speech (need to join), reach out more personally to people on Facebook that I know – but they are more activities than goals and relate more to the vague (have more friends) idea than to the specific measurable goal. Any ideas?
