I understand what you say and feel it too. :) . I am in a profession where I help people get over their demons and inhibitions and difficulties. I understand what you say well. :)
The foundation of the Philosophy of Karma lies in this quote, spoken by Lord Krishna to Arjuna, in the battle of Mahabharata - "Do the action. Do not ponder over the results. To do the labour is in your jurisdiction. Fruits of your labour are not in your jurisdiction." :)
Believing in Karma does not mean that you think about Karma when you do an action. It means you just do what you have to, and what you must. And let the Universe balance the equation as it must. To give and to help because that is what the heart says, is the beginning and end of the story . :)
