Im wondering why culture citizen didn't answer my question....
I'll ask again....What do you think motivates people? Answer that question honesty and you will have the answer to why anyone does anything....then all you need do is look at the specifics.
Ah , well , I've mostly lost interest in the thread ... I've been working on the math of the amount of money required to go 100% renewable...right now it would have to be a 50 year project ( it's kind of expensive , so a bit of caution seems to be in order ).
Regarding your questions. Each person has different motivations at different points of their lives . That's my point of view. Although one friend of mine had a twisted reasoning by which even altruism was some kind of self interest. His reasoning : aha , then your brain rewards you for altruism, so there's always self interest as a motivator. The failure in his reasoning of course is that then you get a very fuzzy definition of self interest, so you've just moved the problem one step backward .
Then we get : self-interest , anything that satisfy your interests ( tautologic ) . so it boils down to what are your intersts : peace ? war? drugs? money? women? men? friendship? partying? art? food?
