Answer:
Here are some possible revisions of the sentence that could better show the narrator's feelings:
1. "I was excitedly telling my dad about the thrill I get from starting a new notebook."
2. "I was gushing to my dad about how much I absolutely love starting a new notebook."
3. "I was animatedly telling my dad about the joy I feel when I start a new notebook."
4. "I was enthusiastically telling my dad about how much I adore starting a new notebook."
Each of these revisions adds adjectives and adverbs that convey the narrator's excitement and enthusiasm, helping to better show their feelings about starting a new notebook.
