Great writing, good work, and obviously talented. But...
"bringing in more than $20K a month for over a decade"
"I started freelancing in the ‘90s and [...] had a full client roster and a multi-month waiting list since I started freelancing."
What - not even one month without work set up for the following month/month-after-next? Or one month in 120+ months where income has dropped below $20k? [A decade ago, $20k was worth even more than now]
Now I've freelanced for over a decade, and my best months have been ~$18K - but my average is a lot lower than that. Short of Mr Jarvis having some advantage -- contacts and a foot in the door, ninja networking skills, or a magnetic personality: how are the above two true?
I'm especially curious as his website doesn't show him as an expert in one topic (per @bdunn et al's advice), but more of a generalist like myself. And generalists aren't supposed to make such money.
[Edit: Redid the currency conversion and upped my best months]
