The reality is that our success will depend a lot on the kind of field we choose. Many people keep working hard in the wrong profession and make no progress. It’s important that you understand the importance of working in the right field to show your skill and achieve success. For example, in India, all professions or careers are not well rewarding. Choose a career that has potential for growth and fulfillment.
You should not assume that I am suggesting that you don’t follow your passion or interest and just go for a job everyone is going after. I am saying that you should choose a career which is both satisfying as well as meets your interest criteria.
