It's hard to mention for the POB platform. I've made more, and consistently, on my last two posts than I have in order platforms. I would first commit to writing one or more posts weekly and then figure out the average of your earnings. Then figure out the amount of time it would take to reach your goal.
If the time it takes to reach your goal is satisfactory, then commit to that effort. If you need less time to reach your goal, you would have to create more content during the week.
It's just a recommendation, but one that will serve me in the long run.
