A lot depends on the type of flying you do throughout your career. GA pilots flying bush and charter tend to do more than airline pilots, particularly long haul who seldom do 500 hours per year.
I started flying at 18 and retired at 57 having logged a total of 22,000 hours, of which 11000 were on the B-747.
Doing 800 - 1000 hours per year in the early stages of my career soon tapered off to about 450 per year.
