Perception

What is disadvantageous can be an advantage.

When considered by removing value judgment, the disadvantage can be interpreted as difference or even uniqueness.

The fact that one is different from others means the existence of a gap.

A gap may be perceived negatively from one perspective or measurement, which is in fact not absolute.

By adopting other viewpoint, the very gap can be translated and utilized positively for one's advantage.

Here comes the application of one's creativity.

Disadvantage or advantage, defeat or victory, and unhappiness or happiness are up to one's attitude, perception and vigour.
