My life has become a Disney song

Just the other afternoon I said to someone “How can I write about happiness when I am struggling to maintain it”?
I guess it was a rhetorical question. In any case, my friend didn’t answer me. It’s a bit of a tricky one to answer after all.
What I am learning is that happiness is something that evolves and it certainly isn’t a ‘one size fits all’ type of achievement.
I’m also learning little lessons that I am writing in my book.
Maybe that is the reason for my struggle.
