One should live with both principle and flexibility. Life is like the ocean, constantly beset by storms. When facing resistance, should we fight to the bitter end, or find ways to maneuver and ultimately achieve victory? "Principle" is the backbone of character, providing strength and integrity. "Flexibility" is a treasure trove of wisdom, allowing for tactful handling of situations. In matters of core principles, we must remain steadfast and unwavering. However, in methods and non-essential issues, we should be tactful, smooth, and even willing to make compromises. This balance of being principled yet flexible—knowing when to stand firm and when to yield—is the key to a harmonious life and a smooth journey through the world.
