Hi Jayanthi,
First let me know the level of your knowledge in Hindi. If you are interested in speaking hindi fluently, I do suggest the same as our friends suggested i.e. Start speaking hindi with hindi and other language people, then start watching Hindi serials(for some time atleast), listen to NDTV news and other network, listen Cricket commentary in hindi, words like Ballebaaz, gendh, chakka maara, chouk pada, girgaya, pareshan hai, shandaar shaat, etc., will be most frequently used.
Unless you develop the attitude of learning any new language, it does not come in your way. But, Hindi is very sweet language and you can easily learn it with concerted efforts.
U can also browse through Shabdkhosh.com for English-Hindi translation of words.
AAAPKO HINDI SEEK NEKI TAMMANNA JO HO UTI HAI USKELIYE MERE BAHUT BAHUT BHADAYEE HOO.....
(The very thought that have struck your mind to learn hindi, I heartily congratulate you for the gesture)
Regards.
