Learn Hindi properly for success

Our new generation, starting from 1970, started reading in English medium or Convent Schools, are good in English, but weak in Hindi. Many of this generation migrated to UK & USA, or joined highly paid jobs in India, are successful. But rest of this generation (My calculation more than 80%), are still in India, doing small business or employed with middle size companies or individuals, cannot be treated as successful. If they had studied in Hindi medium Schools like us, with the knowledge of Hindi and English both, they would have scaled bigger heights. I am not cricizing anybody. But I find their Hindi weak. They can not write in Hindi. This generation should take initiative to read and write hindi, to be successful. I wish all our childrens, studying in English Medium schools success.
