Strength is important. Strictly speaking, appearance is also a type of strength.
Nowadays, many people have plastic surgery and dress themselves up beautifully, essentially to increase their strength. In a certain sense, appearance is a way to quickly increase one's strength.
The range of strength is very wide, appearance is only one aspect, and the advantage of appearance will be increasingly weakened as time goes by.
In other words, in this age of looking good, when everyone is beautiful, other aspects of strength are particularly important.
The sun will always set, and the beauty will always fade away. Improving inner strength is more important.
Appearance can only temporarily overtake others in corners. If you want to stay ahead for a long time, your overall quality must keep up, and then you have to talk about your strength.
