### Explanation of Changes.
1. **Find Method Instead of Regex**.
   - Instead of using regular expressions, the `find` method is used. This method is generally faster for simple substring searches.

2. **Simplified Logic**.
   - The logic is simplified to look for the substring `\n\nAction` or `\n\nFinal Answer`. The first match found is used to determine the thought section.

3. **Memory Efficiency**.
   - By avoiding the complex regular expression and using simple string operations, the program uses less memory.

This rewrite should result in a more efficient execution of the `_extract_thought` method.
