"The grand essentials to happiness in this life are something to do, something to love, and something to hope for."
~George Washington Burnap, [
The sphere and duties of woman : a course of lectures]
I translated this into geometric form - "The Triangle of Happiness"
This one approximates philipma1957's triangle.

The idea of a right-angled “triangle of happiness” is great. It seems to imply that our lives also move forward with three corners: work, love, and hope. These are three important like directions, wherever we turn our eyes, their imprint is there.
If we look at history then we can see that whether it is a great creation or a difficult struggle these three corners of the triangle have worked in the background of our life. Love does not run straight like a curved line of geometry, sometimes high, sometimes low; yet within it lies the continuous beauty of illusion.
Life is also full of ups/downs. We learn to maintain balance as we walk the curved path of rules and regulations. When viewed from a distance, the “triangle of happiness” seems like an engraving on the wall of an ancient temple that has survived time, and is silently teaching: many things are beautifully maintained in the triangular shape.
Finally, this is not just a philosophy point, it is a map of the human heart. Each line tells a story of emotion and the three angles together show what you do in life, who you love, and what you hope for. The path becomes clear.

That's beautiful! Thank you.
Perhaps my idea was too subtle but for my version, I purposely used the right angle triangle and intentionally placed "
" on the hypotenuse (the longest side) because philipma1957 really seems to like keeping himself busy.
