How to start own business after graduation. What should start being an electrical engineer. Simply how to be an effective Entrepreneur?

Electronics Engineering is a good field; however, it would be very challenging to start your own electronics company. As you would likely manufacture electronic components for businesses and consumers, you would need substantial capital investment to acquire materials and hire assembly workers and a large company staff. This, combined with warehouse/factory space means you would be disadvantaged to compete with big-box retail names like Sony, Panasonic, HP, and Dell.  

Your best chance is to work in a Fortune-500 electronics company or support firm that manages product fulfillment for the MENA region.  Certainly the best place to look for a career would be in Knowledge Village, Dubai.  I wish you best of luck in your career.
