The rural people should voluntarily participate in the extension work. Extension work must be based on the needs and interests of the people. These interest and needs differ form individual to individual, form village to village, form block to block and form state to state and therefore there cannot be one programmes for all people.
To be effective, extension work must begin with the interested and needs of the people. Many times the interests of the rural people are not the interest of the extension worker. Even though the sees the needs of the people better than they do themselves, he must begin with the beds and interests as they (the people) see them.
