So i'm having a little difficulty understanding what you mean by your questions.  I think you want me to tell you that in the future you will find your true calling and your struggle will be over.  However first off, to say someone who has a life of hard slogging occupationally is not receiving any assistance from fate would be incorrect.  For some people their karma is to have a difficult life occupationally.  I can explain the karma of such people knowing quite a few of them personally, and struggling occupationally in my life also.  Of course such a karma is usually associated with artists, but it is due to such people attracting such energy by believing that man should be creative.  Thus, they are always in conflict with people and society who believe people should be a certain way.  Such people normally fight for freedom.

Some men who struggled were Mirza Ghalib, Giarduno Bruno, Galileo, Copernicus, Nietzschke men who in their time struggled and in some cases were thought to be crazy. But the largest example is of course Christ who took the full burden of sin upon himself people today really have little conception or understanding of what that means, or what Christ accomplished, but that is how he was able to heal people.  He took the burden of their sin, thus Christ is the man who forever heals mankind.  Similarly men who incarnate and struggle, do they not take the sin of others, yet as Christ always said the kingdom of heaven was for such men.  

I know people who can work any job in the world and they are happy.  They could be a janitor and they will take pride in that, while i also know people who have a job such as a college professor and they are still not happy with it.  Being happy with ones share in life, is something people severely lack nowadays.  I am from Pakistan and the level of poverty there is astronomical.  Yet, most of them know its not what kind of job a person works or what kind of house he lives in, but his actions that is more important.  Of course you will find many poor people who are angry with poverty and will commit crimes, yet if such people with nothing to eat or nowhere to live can be happy, then can the rest of the world stop complaining about not getting that promotion, or getting that car, or house they always wanted, because such complaining will consume such people upon their death.  The tibetan book of the dead explains this idea, as it says that some men will encounter demons upon their death, but it is stated that such men should understand that that is simply their desire appearing before themselves.  Sorry, if i always go into philosophical rants.
