I once dreamed of becoming an engineer. Yep--an engineer. I know for a fact that the richest countries in the world does not necessarily have the best lawyers (Third World countries have lots of good lawyers circumventing their laws). They do not have enough doctors, for they still require the assistance of Third World countries. So, no, it's not them, either. What makes a First World country a First World country is its pool of scientists and ENGINEERS.
Think of the Industrial Revolution. This event in history decided who will be the world's superpowers in the 20th and early 21st century. Great Britain started it. Its eventual use of machines to create products made it possible for them to mass-produce goods of top quality--making them one of the world's major producers of these goods and eventually prolonging their power in today's world. So, where were we? Ah, yes. As I have said, I once dreamed of becoming an engineer, I love mathematics and the physical sciences, you see. And I thought that engineering is the right field for me. I once imagined myself holding some pencil, making blueprints of bridges, towers, highways, and the like. I once imagined myself putting some lead refills inside these drafting pencils after I have finished those blueprints. I once imagined myself wearing some construction helmet, admiring my completed work of art--that is, the building(s) that I engineered.
However, in life, we tend to change decisions when we feel that these decisions are obstructing other ambitions--other dreams. We choose to choose decisions that will not be beneficial only to us, but beneficial to those who are important to us as well. We do not decide solely for ourselves--unless we are irresponsible beings.
In the end, I chose computer science.
