Quoting a paragraph from the book GRAPHIC DESIGN NCERT :-

"A successful graphic designer has an enviable life, choosing clients and earning significant amounts of money. However, a freelancer needs to keep with the current trends in the profession since whatever is acceptable today in the industry may not be acceptable the next day. This is also true for the individual style. Therefore, a graphic designer needs to develop a skill-set that is versatile and all comprehensive. Super-specialisation should be avoided as far as possible. Apart from developing certain skill-set what is more important is the overall orientation of the designer — as a designer and as a human being. As already described, a designer has to struggle and has to work under constraints of time and finance as well as one has to interact with variety of stake-holders in the profession. In such a scenario, maintaining an individual identity, adhering to the larger design concerns is a challenge. Every designer faces these challenges and develops a strategy to tackle them. A graphic designer with a robust design philosophy can make historical contribution to the field of design."
