It cannot be guaranteed that our efforts will lead to success, no matter how much we strive. The plan we crafted yesterday may no longer be relevant today, and the strategies and tactics that helped us in the past may no longer be sufficient. We are confronted with a continuous exponential change in every facet of our lives. In light of this, there are no assurances that our efforts will bear fruit. To achieve our objectives, we must persistently experiment, adjust, adapt, and learn. We must continue to move forward and enjoy the journey, recognizing that success is never guaranteed.
