I see that you are feeling obsolete. I am sorry. You matter. You matter to me and you matter to the fate of this world. You are the butterfly wings whom change so much beyond your comprehension. So. Let that go. Let love in. Realise your worth to yourself. Admit your own value to yourself. At that point you will have the kind of self confidence that is self contained and self protected. You will be a pillar and ready to stand by others whom have achieved the same. Be confident. Start feeling the difference you make. Be willing to see your own gold.
