Mysteries in life are often revealed after the story is uncovered. People not only influence us as they meet us, but leave an impact which lasts for a long time.
When we meet different people, it is difficult to understand the thought process and their arguments about various topics. But only if you continue with that conversation, you see another view point. This view point might open up your mind to another possibility which you might not have considered. It does not mean your imagination power is lesser or you think less. But the line of thought depends on our previous experiences in life. And the breadth of our vision depends a lot on how open our mind is.
Our job is to focus on our goals and keep working in that direction. Learn from past experiences. At the same time, not be biased with the new people we meet now. There is a very fine line between applying what we learned and yet not being biased.
Goals are not constant either. Sometimes they go farther than we think. And at times they come very close quickly, that we lose motivation. Each day we need to find a reason to feel driven to do something interesting, something new that might enlighten our day! Inspiration comes from people with positive attitude and Good-Doers.
