Recreation is difficult to separate from the general concept of [[Play (activity)|play]], which is usually the term for children's recreational activity. Children may playfully imitate activities that reflect the realities of adult life. It has been proposed that play or recreational activities are outlets of or expression of excess energy, channeling it into socially acceptable activities that fulfill individual as well as societal needs, without need for compulsion, and providing satisfaction and pleasure for the participant.<ref name=y3>Yukic TS, 1970, pp. 3f</ref> A traditional view holds that work is supported by  recreation, recreation being useful to "recharge the battery" so that work performance is improved.

Work, an activity generally performed out of economic necessity and useful for society and organized within the economic framework, however can also be pleasurable and may be self-imposed thus blurring the distinction to recreation. Many activities in [[entertainment]] are work for one person and recreation for another. Over time, a recreational activity may become work, and vice versa. Thus, for a musician, playing an instrument may be at one time a profession, and at another a recreation.

Similarly, it may be difficult to separate education from recreation as in the case of [[recreational mathematics]].<ref>Kulkarni, D.
