Hello Jitendra Singh,
Everyone has some strengths and also a few limitations (I would hesitate to use the word "weaknesses").
Like Simhan suggested, you could make a beginning by sharing your experiences as attachments. I think this could be another experience for you—slowly, but surely, you can pick up your English. Like the old saying goes: practice makes the man perfect. When you begin to interact with others in English, I am sure you will soon master it, like you mastered Hindi.
Regarding your comment, "experience is more significant than an expert"—I think you are right. There's a saying: One who speaks from experience shares, one who speaks as an expert shows off. So just stick to your experiences, and I am sure all of us on this wonderful forum will benefit.
Like Riyaz mentioned, language is just one form of expression.
While it is important that the receiver understands what is being said (else what's the use of even the most beautiful thoughts being expressed?), I am sure the members of this forum are tolerant enough of any genuine mistakes made during the effort to improve their knowledge—be it HR or language. That is the whole purpose of this really good forum/site.
In this context, I do not agree with Seema that it is only Indians who have what she termed as "importance." She seems to be mistaken about the basic reason why English is given importance—it is not to replace the home language but to reach out/spread out our limits of interaction in this globalization era. I am not sure if she is aware of this fact: most Asian countries—Korea, Japan, China, Taiwan, etc.—are recruiting ESL teachers by the thousands every year (in fact, the demand for 2010 in a small country like South Korea was 2,500 ESL teachers)—for only one reason: what I mentioned above. So the reason for learning English depends on what priorities we have.
To summarize, Jitendra—YOU SHOULD BEGIN TO POST YOUR THOUGHTS and in parallel try to build up your own command of English. Let this be another refreshing and new experience for you too—which is bi-directional.
Look forward to seeing your posts soon :-)
Regards,
TS
