ethics as a function of efficiency

How can we determine, from moment to moment, which acts produce optimal functioning and which ones don't?
We must assume that the universe craves optimization. By optimization I mean that the universe craves a state of working that is as efficient as possible while using the least amount of resources.
How do humans fit in?
Humans fulfill a function in the universal system. We must because we use resources and if we use any resources at all we must be an efficient means of fulfilling some function. What that function is I can only guess (possibly to provide the universe a self-awareness, or the possibility of some sort of growth) but it can be assumed that the universe is a system with an inclination towards progress (e.g. the arrow of time) and that it prefers to make that progress in an efficient way.
How does an element in a system knowingly fulfill it's function in an efficient way? First by noticing its role in the system. Humans can notice what function suits them best by simply looking back over the years of their lives. We all are presented with situations and choices in our lives that reflect an undeniable individuality in everyone. Our inclinations, humors, passions, distastes, are all manifestations (when differentiated from neuroses and misapprehensions) of our own most suited function. Once this is recognized each individual can then ask themselves, moment to moment, whether or not they are efficiently fulfilling that function or not. So called "virtue" then rests with the choice of whether or not to act in accordance with that function and "wickedness" lies with the impediment of the universal progress.

This is my first rough draft of this theory and over the coming days and weeks I'll be presenting new details and support. If you find anything wrong with it or just want to challenge something about it feel free to leave comments.
