If I may offer my opinion: first I enjoy very much your wonderful and uplifting posts. Second: perhaps if you find yourself losing it, it is because you're so attached to the result of the end machine changing this. I only recognize this because I am guilty of the same thing too often. Yet I am inspired by several (including Byron Katie) who live in the now and to be peace and light, you cannot be attached to the outcome of your efforts. To be attached to outcomes is by definition not living in the now. Yet when you enjoy being holistic and reaching out with love, you can enjoy the act of doing it with the fond desire that it help and the expectation that it will only help when people are ready - and being okay with that knowledge.
I think you already do much of this; the only thought is by letting go of the outcome itself, you become less like the machine and more peaceful. Take care~
