Never be on the wall. Never be undecided for long time. You can be a player or audience. But you cannot afford to spoil someone's dream when you are undecided or when you decided to stand on the wall (to join at anytime). It is so much energy sucking.
Being on the wall gives us feeling that we can chip in at anytime but then the folks who are already playing the game would feel that you are an alien.
If you want to be included, you will have to absorb risk. You cannot avoid risk and expect a reward at the same time. Be wise.
Choose the game - play it or watch it.
