I'm looking for a word that describe a person for having a gentle joy for being diligent. For example, a person spends their time and effort to learn a new word every morning. He does that because he believes that his vocabulary will be expanded some day, although there is no clear evidence that he will need to learn that word. One day, he meet that word and can recognize it without asking what it means. He has a gentle joy because of that.
What is the word for that joy? The word should have the diligent sense in it.
- What keeps you consistence on learning vocab?
- I give me a gentle joy for being diligent, a _______
I have checked all of these synonyms but all of them cannot apply. They don't have the joy sense in it: conscientiousness, assiduousness, assiduity, hard work, application, concentration, effort, care, industriousness, rigor, meticulousness, thoroughness; perseverance, persistence, tenacity, dedication, commitment, tirelessness, indefatigability, doggedness
