The reason behind an action is what makes it either good or bad — and that same reason is the power behind continuity. When the reason is right, forceful, and motivating, setbacks won't be able to stop the progress, no matter how many. But drifting actions can be stopped by even the slightest, lightest obstacle.
People who cross the finish line have their eyes and minds set on it before they even start — that has been the motivation behind every step. Those who finish life's race successfully overcome many obstacles and step over many setbacks because their life's purpose pulled them along. Drifters along the journey of life have no steps to trace, no stories to make history, and stop at any junction they're stopped at.
To have a meaningful life, you must live for a reason. Know where you are facing in life, and face it squarely to overcome every obstacle.
