Why must we have confidence and perseverance?

1. Perseverance is probably a lasting psychological state of doing things.

2. Self-confidence is an optimistic attitude towards successful behavior or accomplishing something.

3. The relationship between self-confidence and perseverance is a non-inclusive juxtaposition and belongs to a psychological state.

4. Especially the progressive relationship, the object of expression belongs to the relationship between inclusion and inclusion. For example, I like painting, especially Chinese painting.

From the above point of view, my fifth point is clear and inevitable, that is, "special" cannot be related to "confidence" and "perseverance"

So my conclusion is that "perseverance, especially confidence" is grammatically incorrect. Maybe it's not Madame Curie's fault but the translation, but it's impossible for everyone to make mistakes in translation.
