Indulging In Business Confusion

Some days I feel like I know exactly what I need to be doing, but most days my brain indulges in confusion. I’ve considered going back to basics and doing a download and doing the ideas a reality. The thing that keeps coming up and is consistent with my actions is something around writing and illustrating, yet my brain is adamant that this is not the right way to go because this isn’t feasible because “how will I generate a monthly revenue from such activities?”.
I don’t know if my brain is right or wrong. help.
