The brainbows are strong in the Steemverse.

Having access to happy memories is important. We live in the past, present, and future. Having a memory bank full of good memories is nice.

Someone may say, "Well, I don't have that many good memories."

This makes me think that happiness is a state of mind. A happy person will train themselves to pull good memories from anywhere. You posed a good example. Your good memory just came from one shower.
