We all have great ideas sometimes.
People with a scarcity mindset believe good ideas are rare, and they need to be hoarded. When one such person has a fantastic idea, they will protect it and keep it a secret. But since their idea isn’t exposed to the world outside, they receive no feedback. No community builds around it, and this idea doesn’t multiply or gain traction since it isn’t shared. This only confirms their belief that great ideas are rare.
People with an abundance mindset believe that good ideas are aplenty, and they need to be shared. Such a person will share good idea with the world. The world responds either by ignoring it, or by grooving with it, sharing it and improving it. A community builds around this idea. It merges with other ideas to give birth to new ones. It is only a matter of time before the same person has another great idea.
It is true that great ideas are rare. It is also true that they are abundant. You get to choose.
