Parenting is the toughest job in the world.
Why?
For one thing, you never truly master parenting. By the time you make sense of one stage of your kids’ lives, they’ve already moved on to the next. One minute you’re a Ph.D., the next minute you’re starting from scratch in “Parenting 101.”
Parenting is also tough because you can never resign or retire. From toddlerhood to adulthood, your role as a parent will change, but parenting itself never really ends.
