Asking people to change is hard. The person asking for change might be asking others to move 10 steps ahead. The people being asked to change
1) Might not be convinced
2) Think it’s too hard and unknown
3) They don’t trust the person asking them.
My experience in persuasion is to first build that trust through many small acts. Once the trust is there, then the conversation can start about change. Trust is in credibility difficult to build especially with people who you don’t work with daily. So give it time and patience. Start with trust, then move to step 1 and step 2. That’s it, this is short, I know.
It’s for me, not for you.
