Hard-driving,  abstinence/self-constraint are both considered self-control and self-discipline. Among the hundreds of people I consider comparable, my relative strength lies slightly more in abstinence … 95 marks there, vs 80 marks in hard-driving.

I think my sis is stronger in hard-driving.

I think my dad is strong in both !

— Buddhism, wellness … emphasize self-constraint and abstinence

eg: early rise. Many can’t persuade themselves to sleep early
eg: slow jog of grandpa
eg: absorbency

— achievement, learning, academics, competition, athletics .. emphasize hard-driving.

eg: interview muscle building
eg: localSys
eg: yoga

–Some domains require combo of the two

eg: refresh past learning
