My biggest takeaway is setting up a funnel that disqualifies people from participating unless they comlplete the tasks. This is very innovative and I love the concept. I actually thought about copying this strategy before you said it in the video :)
My biggest concern is ensuring that I am attracting the right people from the start. Also I am concerned about disqualifying people if they message me with very just cause like someone died or they got very sick etc. What would you do in such circumstances?
