I am supposedly an optimist as characterized by my friends. Unless otherwise confined by the limits of foreseeable reality, I think one can succeeed in things that they are passionate about. I read in a book once that if your career is based on something that you are passionate about, irrespective of the monetary benefits that you might reap out of it, you will still enjoy the journey. I totally agree to it.
We often try to look out for the formula behind successful people and try to follow it as much as we could. But, in the process, we often sacrifice our interests into achieving something that we dont really like. You will be overwhelmed at how passion can lead you into achieving things that you only dreamed about. When I mean passion, I dont just talk about the goal, but the intent to put all the efforts into making it a reality.
One of the interesting things that recently captured my attention is that, if you pick any two distinct numbers, irrespective of what they are, you can always find infinite numbers between them. Same is true with time and for that matter, anything that is continuous. One way to view life is to take any two points in time and see what you did during that time. If you follow your passion (which will be continuous), doing whatever you do makes it infinitely worthy. Now, that is a life I choose to live by.
