Hello Josh
First, 20-50k monthly is not at all out of reach for many affiliates, some of the largest make 6 figures monthly, I personally know two different people who have had, and regularly have 40k months. Myself, while not in that range make in the low 5 figures monthly, this is after 11 months, and it only gets better each month.
So find what works for you and keep at it, it will pay off.
