The maximum handicap an office worker can achieve

No matter the hobby, reaching the top level
requires a lot of time and money,
but golf seems to be the most extreme.
Even those with great athletic ability who reach single digits in a short time
eventually hit a limit due to time and financial pressures.
I have been playing golf for nearly 20 years,
and in my experience, I believe the maximum handicap an office worker can achieve
is around +7 to +9.
Unless you give up your main profession,
it is difficult to lower it further.
A close older brother of mine has a handicap of +3
and has been a club champion twice.
What he says is that
among people with proper jobs,
there are no champions.
