Controllers Are Obstacles In Front Of Your Goals

Having focus on a personal project, mission, goal, and/or task is one of the "happiness" or "contentment factors" for a healthy human being.

This does include playing a personal role in a larger project, mission, goal, or ongoing organization. 

Since this is a significant factor for the health and happiness, confidence and fulfillment of healthy humans, it's also a target for bullies, controllers, and Narcissists.

If they can prevent a person from progressing toward their own goal, they feel powerful, and indeed gain a kind of power over the person.

If they can prevent and block a person from participating and contributing their personal abilities to the larger group, family, project, community or organization, they have successfully sabotaged several things that would have been beneficial, even essential, for that person's well-being, health, and growth, both present and future. 

One of the creepier examples of this is when a controller tries to prevent a parent from caring for their own child, guiding their own child, teaching their own child real values and ethics, and supporting and protecting their child.
Also, trying to prevent a person from caring for or about their spouse or partner, friend, or other relative.
This clearly demonstrates how the desire for control over others has absolutely nothing to do with "making others do the right thing because they don't know any better".

When others stand between you and a personal goal, (POSITIVE goal, that is), a project, mission or task, whether it's caring for your child, rescuing an animal, buying a home, getting a job, singing a song, going to school, building a shed, learning an instrument,  or painting a picture, they are not trying to "help", they are trying to insert themselves in your business in order to get a fix of control, and to block you from progress.

See it for what it is, and go around them. Block them out.
If you have to, go do what you were doing somewhere else, away from them.

You may want to involve them, or to get their approval, because you know that letting Controllers believe they're a part of something you're doing (and getting credit for it, and leading) means they're likely to do less to block you. But that's an illusion, they'll still block you or try to control you, they'll just do it in more of a Passive Aggressive way. Controllers don't comprehend boundaries or respect, so it's inevitable. If they're involved in any way, they WILL try to take control at some point, and if they can't, they'll probably cause damage instead.

Keep your goals, projects, missions, tasks and activities "online", don't shut them down in order to avoid a Controller's consequences. Go around. It does take more effort than if there was no Controller in the way, but take it for what it is, an obstacle on the course.
