How are thinking, speech and human activity related?

All these actions as thinking, speech and activity characterize a person as a person. All these actions affect his socialization in society. A person’s thoughts can be transformed both into speech and into certain actions (activities). All these actions are also inherent only in man, in their totality we are people. People are social beings, and for this it is necessary to somehow express their thoughts, somehow communicate, it is possible to somehow influence the environment, i.e. carry out certain activities.
