For carving out a career in todays crowded streams, it requires deep thinking and pondering as similar career paths may diverge significantly in the long run. After completing class 12 there are innumerable possibilities in the field of engineering, commerce, law, management, humanities, science, medical and many such areas which have their own fascination. The first and foremost thing is identifying your interest and passion which you have already indicated as design engineering. Now when you read about other career lines you will see many information regarding other lines as well as the remunerations and that will not be easy to decipher at this stage because there will be many things hidden there especially the path of hard work and persistence which leads there. Assuming that a person can tow his interest line magnificently it is better to stick to that and even after doing the design engineering course you can add on the various computer packages in your qualification and then switch to a computer area connected to your core area of designing.
Mechanical engineering is the oldest branch of engineering and has evolved in a big area encompassing the understanding of mechanical machines to the designing of new ones where not only the mechanical concepts but everything from electrical to computer technology is embedded. So learning design engineering is going to be a learning of so many connected fields of science. Some of the areas are progressing in leaps and bounds where the mechanical engineering comes at the forefront and some of them are aerospace engineering, automobile engineering, mechatronics and many more like that. Robotics and artificial intelligence are combining all the knowledge and engineering in one compact process. Today industry is progressing in a direction where many disciplines are being merged in designing a new machine and a design engineer by default will be learning all facades of engineering and scientific principles. Automation is coming everywhere. This gives one an opportunity not only to excel in ones work but also to switch jobs to the greener pastures.
So, what I will suggest is stay in your interest area, work hard and try to be the top scorer wherever you study or work and then success will come to you in a big way. Doing design engineering does not force you to remain there throughout your life. It is not so. Today disciplines are tremendously overlapping with each other and you will be surprised to find that when your skill levels reach that stage. With time one can align oneself in the directions of better salary packages and better positions in the career ladder but today one has to focus to acquire the needed strength in the area before becoming able to negotiate the remunerations and perks with the employer. First come first and this is the time to concentrate and focus to excel in your interest area.
Knowledge is power.
