Nothing happens quickly. I also think there is a correlation between intelligence and stubbornness.
Others have often called me intelligent. I know I am stubborn.
I've observed that people I consider intelligent are stubborn as well.
We are used to people not thinking around us. Thus, we can get into a mode where we are quick to cast things aside that challenge our world view.
I have been trying to keep that aspect of myself more at bay. I think it needs to be there a little bit but not dogmatic like as it also keeps us from blindly accepting things we hear.
I also realized long ago that it is very rare for someone to immediately change their mind. It takes time.
The analogy in my mind is always that I am throwing mental seeds as I talk to people and they are throwing them back at me. Some seeds may never grow. Others may eventually sprout and do something. Perhaps not what you planned but they will lead to change.
oh I'm well aware of the 'planting seeds' strategy and have virtually done it for years, throw out a handful of seeds and run. I no longer fret about whether people listen or not I just post and let it brew. I gave up debating online and only answer genuine questions if I know the asker is open. I can spot a shill a mile off and never engage.
