I did not expect parenting to train me in the skills of an assassin. Beware anyone with children, especially multiple children under five, for they can put you in the ground.
Parenting trains you to read body language; to learn your target/child's little tells. The covert yawns, the easily missed screaming, which indicates their moods. It's important to see what they need so you can deliver it. This minimises suffering - yours and theirs. Parenting is a crash course in radical empathy.
It also teaches endurance. You need to outlast the child you are rocking. If you microsleep before they doze off, the slump will wake them and it's back to yawn one. Channel the patience of the hunter in their hide. Patiently waiting. Focused upon the perfect moment to put their prey to bed.
You will also become more dextrous than you imagined. You will hold a bottle, two toys, and a child - without noticing what you are doing. Each little goal requires such effort that the amazing things you do for that goal are hardly worth attention. Throwing knives is easy mode. The parent catches and holds things for a target who must not be disturbed in any way.
Finally, the parent learns commitment. That some causes are worth any amount of indignity or wading through fluids. Especially the cause of love.
