And being "capable" in the first place is largely due to luck also. What is being "capable?" Intelligence, education, discipline, motivation? Intelligence is largely genetics and your socioeconomic status as a child. Education? Intelligence plus socioeconomic status as a child and young adult. And a fair bit of luck too (i.e., admissions, etc.). Discipline? Parent's socioeconomic status and probably some genetic/psych/environmental influences. Point being, just being capable of being "capable" has much to do with things outside of your control. Most are unaware or dismissive of this. Goes back to the old adage of being born on third base and congratulating yourself for hitting a home run.
