please review My letter of motivation

Motivation Letter
Dear Sir/Madam,
With this letter I want to explain my motivation to continue my study for a higher degree.
In 2012, I obtained bachelor degree in Electronics and Communication Engineering from Ahmedabad Institute of Technology affiliated toGujarat Technological University, India and predicated as very satisfactory.
My ultimate career goal is to become a successful Automation Engineer. With that aim in view, I would like to pursue the Master program in Bremen University. After pursuing The Master degree, I would like to work in Automation Sector.
According to my knowledge, in my country India, We do need to develop Automation Industries as most of CNC machines and Automation Technologies are imported In India. So I want to make India self reliant in Automation Technology, in that way, serve my Country in that field of Technology.
When I was pursuing bachelor degree, I came to know about Automation Industry, I visited Machine-Expo 2011 in my city, and I saw many automatic machines. Then after, I visited some factories. And on TV, I also watched Mega factories show on National Geographic channel, in that Show; they show us how big companies like AUDI, BMW make their product by using automatic robots. Those are all the factors that influence me to study further in Automation Engineering.
I am interested in technical field since my childhood. During my school days, I was greatly interested in making science project. So I was actively taking part in school science fair. And at my home I was always in search for making new things from waste materials. Apart from study, I always watched Infotainment TV channels like Discovery channel, National geographic channel. The shows on these channels always enthral me to go for technical field.
During my bachelor study, I was active in participating in technical events organized by other institutes. I have participated in six different Technical Events. And I was a winner of Robo-Aqua event in Techno-aspire 2011(Technical Symposium) held by Vishwakarma Govt. Engineering College.
During my bachelor study, I was active in making projects. I have made different projects pertaining different topics. The projects of micro-controller were the base for me to understand embedded systems and Automatic Systems. That has helped me lot to enrich my technical skills.
Currently, I am a trainee at Sofcon India Private Limited. This company provides Industrial Automation Training. Apart from Training, I am helping my junior students to make project. I am also interested in solving technical problems in low cost manner in day-to-day life. For example, to make fan regulator made of power electronics. Such a solution is very cost effective and energy efficient. Overall, I am the person who is only devoted to technical field.

I hope with this letter I revealed my impetus and my desire to continue my study. I feel confident that my qualifications are more than sufficient and that I am able to meet the postulated and the forthcoming demands.
Sincerely yours,
