If I were to give an analogy to explain what I am saying above, this is what I would say.

It is like Nepal, my relatives, my childhood friends, the neighborhoods I grew up around, the smell and taste of Nepal, all these things are like magnets. And within me, are pieces of iron. And when I go to associate with all the above places in Nepal, then the iron in me starts to fuse together. And the fused iron within me starts to get polarized by associating with the outside magnet (all the familiar places of my childhood).
So it is almost like the outside magnet has the power to turn my inner magnet on. This is when I am at my motivational best.

On the other hand, the longer I am living in America, my inside magnet is no longer associated with the outside magnet. Why? Because all the stimulus from my childhood is in Nepal. And so my inner magnet gets weaker and weaker. Gradually my inner magnet starts to disintegrate into iron pieces. And in the course of running around all over the place and associating with all kinds of people and identifying with so many activities I feel I have to do, the iron pieces are jostled all around and spread out within me.

I feel this is when I lose motivation and am at my motivational worst.
