In the given sentences, the intensive pronoun is "myself."
Here's why:
1. An intensive pronoun is used to emphasize a preceding noun or pronoun. In this case, the pronoun "myself" emphasizes the subject "I" in the sentence.
2. Intensive pronouns end in -self or -selves, and they are not necessary for the sentence's basic meaning. They simply add emphasis.
3. In the sentence, "I myself am enjoying new challenges," the word "myself" is not essential for the sentence's grammatical structure but serves to emphasize the subject "I."
Therefore, in this context, "myself" is the intensive pronoun.
