Speaking for myself, although I never expected that I'd pass on hard skills to my child (unless they showed a particular interest), at least up until 2019 I felt confident that I could guide them in a general direction to be successful in life. How to do well in school, how to develop a work ethic, how to learn and pursue the things that interest them, how to approach planning a career, how to market their skills, how to manage risk, how to balance doing what they love vs what pays the bills, how to approach relationships... things like that. Regardless of whether they wanted to become a piano tuner or a park ranger or an astronaut or a homemaker.
But right now I know almost nothing at all for what to tell them. I don't know if any moticum of the experience I have that put me on a successful path will be valuable in the future at all.
Basically my plan is to just spend time enjoying time together and having fun, and cross my fingers and hope that things turn out alright.
