Hi Jerry,

What a lovely sonnet to happy thoughts indeed!
I only have a few little nits to share for you to T & T as you wish.
I am not used to seeing sonnets as one long stanza, but it's not to say anything should be edited.

Usually, I see them in a group of 8 lines (the octave) followed by a group of 6 lines (the sestet), OR in a common English form of 3 quatrains followed by a couplet. The closing couplet always summarizes the poem and I do like yours here. YES, please DO share your poet's heart!

QUOTE
By taking Shakespeare’s quill. And then I write,
Maybe in this line I would change to 'And so I write'.
QUOTE
That whine about past loves, and themes so trite,
Maybe change this line to 'or themes too trite'.
QUOTE
When gladness fills a poet’s heart, then share;
Self-pity falls on ears that do not care.
My only suggestion for the couplet is to perhaps change the word 'then' to 'I'll".
Enjoyed the read!
