My life my morals

Morals of a persons are specific to himself. My morals are negative in nature; that is they define things not to do. Furthermore, perhaps my morals are the minimalist subset of what a normal person's might be. Here's a key principle that can define most of my morals.

1. Never do a thing to a person that you won't like to be done to yourself. In case you are expecting an unfavorable action from the person, it's permissible to take a similar action that avoids the unfavorable circumstance for you. The unfavorable circumstance created for the other person should be less or equally severe to the unfavorable circumstance that you expect to be created by the person. The order of severity for the other person is same as yours. 
2. Never do a thing that, if extrapolated, makes sustainable life impossible on the planet. By extrapolation I mean that if every person on earth starts doing the same thing. 

The first principle enforces the morals of honesty, equality, healthy competition etc. but allows the possibility of self defence. The second principle enforces global responsibility like fighting against global warming etc. Interestingly, second principle classifies voluntary celibacy as immoral.
