This is all awesome stuff. Benevolence, charity, helping others ... it makes the world a better place.
Do I consider myself an altruist? Not really. But technically I do not gain anything except of feeling that I did something in my life more meaningful than making money.
This proves you're not an altruist. You benefit from your benevolence, and you should. Altruists don't benefit, and don't seek benefits. Helping others is a good thing. And God knows the people in Venezuela need some help.
Well. If feeling good about doing some good dead is benevolence, then surely I'm not an altruist. I never really cared if I fit this category anyway.
All the best my friend
