Hi Harshit, yes everyone fends for oneself. This is a natural by product of a competitive world in which the competition will only increase with time. However, building a good network is absolutely imperative. Why? because networking will help you develop and improve your skill set and stay on top of the latest trends in your industry and job market. Networking also helps you to advance your career and gives you access to more job opportunities. The more you network, the more you'll grow and learn how to make lasting connections. People will communicate and help you in your career if you show the passion, enthusiasm and persistence.
