When thinking about it, I think the difference is passion. Not passion for the outcome. Not passion for the goal. Passion for making a difference in the current existence. Passion for the attempt at understanding and striving to know more than what is physically possible. This ends up super seeding the current situation, and eventually leads to problems. However, the confidence within will always outweigh the confidence of those without the passion. There is my justification. For everyone reading this in confusion, try and interpret this in your own life. As for me, I need some sleep.
