A coach and a therapist are, first of all, an authentic manifestation and characteristics of the person and personality you choose. His education and experience of a person with whom you have resonance on topics that are important to you. In addition, this is a set of practices, skills, and tools through which a specialist can help you get from point A to point B.
Let's look at the example of a metaphor. You live in a house with a kitchen, a living room, a bedroom, a garden, a basement, and maybe a barn. And at some point, you want to clean it up because the dust and scattered things are already making your eye twitch, or build or demolish a building. Depending on this task, we can find out that you need a cleaner, a welder, an installer, or someone else. It happens that to go into the basement and get a valuable thing that is needed to achieve the goal; you first need to clear the entrance to this basement, turn on (or even fix) the light, look around, understand where to look, and find this very thing. You can do this alone and be afraid to go down to this basement for a long time, or you can do it with someone with a flashlight and the right tools.
