When the solder flows just right
So you sold your soul to the devil
Breaking the seal on a new jar of coffee!
On the same note, making a V60 pour-over brew.
A nice, smooth downshift.
When I am at a hotel and the pillows are exactly the thickness and firmness I prefer.
When avocado is soft enough but not overly ripe.
When I see Pomeranians smile.
Peeling the temporary screen protectors off new electronic devices
When you drop one spoon full of some stuff on a scale, and the reading is exactly what you were aiming for. Basically a hole in one, but with three digits of precision.
When there are a bunch of bicycles driving (especially in the morning rush hour) and somehow they don’t crash into each other and then there are also another bunch of bicycle coming from the side but they somehow just flow right through. For some it might sound like a nightmare, but you did ask for something oddly satisfying :)
