"If your path is more difficult, it is because of your high calling"

The more I ruminate on this the more it rings true.  However I would substitute 'difficult' with 'unique'.  

Some well meaning friends used to advise me :  Do not specialise too much in one area, because the more you specialise in one area, the more difficult it is to join the mainstream.   It made sense to me but never really affected my choices.  To begin with mine is a unique subject and jobs cut out for it are indeed rare.  Even the few jobs do not really give one an opportunity for personal growth.  But on the flip side, a lot of my growth depends on how I improve my knowledge, outside of the job area.

And certainly I do feel a very strong invisible pull to my subject.  Right now I do not know perhaps that it is my calling but in the past whenever (more specifically on two occasions) I have tried to switch areas somehow it has not materialised.  And it has not been painful at all!  Thats the awesomeness of it!  Both times I have landed with better opportunities to learn and grow.  That s why I call it 'invisible'.  I certainly don't see it but it does exercise a strong pull.  Its like whenever a child tries to wander off from its nursery, the mother gently but surely makes sure it does not go astray and puts him back in his nursery where it is safe for him and where he can learn a lot.
