What make differences in the quality of people's lives?

Decisions
The main factor that affects our lives is how well-defined and powerful our decisions are. It is not only summarized in simple decisions like daily plans, but can go further to define who we want to be or what we are urged to achieve in in our lives. Our future lives, our job and our family are all dependent on how significant our decisions are today.
I remember as a child I always wanted to learn another language or study overseas. Everyday I took some time to imagine that I am in a foreign country with a different language and culture. I focused on what I always wanted and then by by the help of my family I could reach it. Then, I started studying my pre-university in college.
I came up with new decisions and I wanted to be the best. I tried to do my best and I was known as the second best student there and now I am studying Bachelor of Electrical and Computer Systems Engineering. I always dream that I am having a great job with a superb salary.
I have now achieved some of these dreams and confidently planning to handle all of the difficulties to be the successful man that I have always imagined in my mind.
Now, the thing is we should not be over confident after reaching our primary dreams. In addition, dreaming has no limitation and when you imagine, your mind should break the borders of infinity and that is when you can realize who you really want to be or what you are born to achieve.
Having heroes in life can aid us to follow their character properties. Heroes are always known as the symbols of determination, persistence and infinitely many other characteristics. Your hero's way of life can be like yours and even you can make a better life for yourself than whomever you like.
