What if everybody did it? Before taking an action, apply the universal law formulation. Ask yourself, if this was applied by everyone, everywhere; does the action still work as intended or does it all fall apart?
One such action that I believe does survive the universal application is altruism.
However, I offer that it needs a slight modification. By selflessly caring for other people and their wellbeing, we still must consider ourselves, just a little bit. In our focus on the other, it only continues to work when we are in a safe, consistent environment. It is a matter of degrees really.
Our focus at the time is on the other and their needs. But attention is ephemeral and impermanent. At the time of the act it is everything. The person we care for is all that matters. We do not consider the ends or the means, only the needs of the one. When it is done, we go on our merry way. We don't dwell on our own righteousness. We do good because it is the right thing to do. Especially when no one else is looking.
