Dear Ramesh
Its good that you came to this plateform with your problems, BUT I can see that most of the POINTS are not your problem but it is your Ignorence which I am trying to explain below
(I am basically from village) You are from a village this not a problem, Every one has his roots in the village. Does some one told you that you are from village that,s why you are not suitable for this job?
(1. my communication problem) ----- Take an english news paper, go to lonely place where no one can hear you, Read the newpaper Loudly so that your sound may go upto 50 meters, Try to bring out the words in the same way as the news reader in BBC. Practice for every single word, After 2 days it will become very easy for you, please try....
(2. i am MBA but i am helping so many people by not take any benifits and by wasting my time so i am as like as MSW so my question is it right by doing this?)----- This point I am unable to understand, Please explain, It seams that this is not a problem
(3. i am talking so much without thinking how can i overcome?)------It is very good that you are talking too much, This is a good thing keep it up, Every one likes talkative persons. BUT
The problem is that you are not thinking, so it is simple just start thinking, I AM SURE THAT WHEN YOU WILL THINK YOU WILL NOT BE ABLE TO SPEAK, (In HINDI old peoples say-- Beta jab Sochoge to tumhaaree Boltee Band Hojayegee).
(4. i want to improve my english communication how can i do without wasting of my money ?)--------Read English new papers in the same way as I said before and compare your speaking with the BBC news reader way of speaking.
(5. i am from village due to my enviornment i am not able to cope with that please suggest me.)---------You are from a village this is not your problem, The problem is the peoples around you. Be with the peoples like whome you want to be.
REMEMBER THAT----- If you will sit with a Foundry man, and if you will loose nothing then Also atleast you will get Black smoke, dust and heat. BUT If you will sit with a Perfumer, and you will gain nothing then also atleast you will get the good smell of perfumes.
I Know this is very hard to undersatand but this is true.
Best of Luck
