请根据以下提示，并结合事例，用英语写一篇短文。
We can go as far as we think. The great minds, more often than not, think more and have more aggressive ideas of their life than ordinary people.

One possible version:
What we think is our direction and a goal of advancement. It guides us and makes us know what we really want and where we go. Then we spare our efforts to take active steps to make our dreams come true.
For example, Thomas Edison had a dream. He dreamed of a lamp that could be operated by electricity, and began where he stood to put his dream into action. Despite more than ten thousand failures, he stood by that dream until he made it a physical reality! And today, his dream lights up the world at night.
We think. We choose. And as we think and choose, so are our lives formed. In the end, forming our own destiny is what ambition is about.
