Hello Jitendra Singh,
Everyone has some strengths & 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. And I think this also 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 would soon enough master it, like you mastered Hindi.
Reg your comment:"experience is more bigger than 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 & I am sure all of us on this wonderful Forum will get benefited.
Like Riyaz mentioned, language is just ONE form of expression.
While it's definitely important that the receiver understands what's being said [else what's the use of even the most beautiful thoughts being expressed?], I am sure that the members of this Forum are tolerant enough of any genuine mistakes made during the effort of improving their knowledge--be it HR or language. That's the whole purpose of this really good Forum/site.
In this context, I wouldn't agree with Seema that it's only Indians who have--what she termed as 'importance'. She seems to be mistaking the basic reason why English is given importance--it's 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 S.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 & in parallel try to build-up your own command of English. Let this be another refreshing & new experience for you too--which is bi-directional.
Look forward to seeing your posts soon :-)
Rgds,
