(I know that’s not really a word, but it is a philosophy)
It’s OK if you’re single, do things that inspire yourself and be creative and make grand gestures and epic pronouncements.
If you’re in a committed partnership, keep the spark alive by doing unexpected and spontaneous things.
And if you have multiple partners, the serotonin and dopamine from being with one can spread to your relationships with the others. As Spider Robinson said, shared joy is increased.
