I think this points to two very important things about investing and trading regardless of EMH.
psychology of the person
We tend to note the loses we avoided (that is the money we kept) much higher than the gains we missed (the money we actually lost by not playing in the game).
Unless someone has a good plan for how to manage and overcome those two aspects of their own mind I suspect they will find it difficult to ever commit to any investing or trading program/​strategy. It will not take too much to push them back into the behavior reflected in your comments.
