by Carey Nieuwhof:
1. They come on too strong. In my experience as a pastor, the people who show up and want to make it headline news are rarely (I'm being generous here) healthy people.
2. They give you advice during your first meeting. Whether it's a casual conversation or even a job interview, people who tell 15 ways you can improve your organization or your speaking often end up being toxic people.
3. They tell rather than waiting to be asked. Naturally, we all have opinions that are valid. But in a healthy human relationship, we reserve opinions about others until we are asked the share them.Toxic people rarely do.
4. They want to be the centre of attention. They hijack conversations. They never ask questions.
5. You hear from them far too often in the first month. Often a toxic person, because they want to be the centre of attention, will try to get on your calendar soon.
6. They have a track record of moving around. Usually a person who comes on that strong has a history of moving around.
