I actually found the Article quite interesting and Inspiring. I know my personal goal this year was to clear $100K in domain sales after market place commissions and fees, but before renewal expenses.
So far I am off to a decent start for 2022.
I start the year off with $5182.30 after fees / commissions on payment plans from domain sales in 2021, that I will receive this year.
I have had 5 retail sales so far this year for $13,170 gross sales, - $10,429.40 net after commissions / fees. So $15,611.7 net sales income thus far. (Obviously payment plans could default, but all but one have paid more that 50% already so pretty confident they will stay the course). Acquisition costs of 5 domains sold in 2022 so far $80.64
I share all this because my names not probably any better than his from article, but to also say I think it's doable to get there. (3 where closeouts and 2 low priced backorders)
