We all do good things in this world. Although most of us believe in Good Karma we do these things not necessarily with the expectations of receiving positive reinforcement for those actions. As children we needed awards or punishments, praise or blame for our actions, but as we evolved in life & reached a higher level of consciousness we forgot all of those things. Most people will do anything & everything to help benefit other people and whatever is moral according to our subconscious (not every action is methodically planned & executed).
I hold hope in this world that not everyone is looking to get ahead - that genuine people still exist. In love, friendships, career, & financially is it not better to act & expect nothing at all in return?
