Set your sights high, the higher the better. Expect the most wonderful things to happen, not in the future but right now. Realize that nothing is too good. Allow absolutely nothing to hamper you or hold you up in any way.

I believe psychology has done very well in working out how to understand and treat disease. But I think that is literally half-baked. If all you do is work to fix problems, to alleviate suffering, then by definition you are working to get people to zero, to neutral.
