.苏东坡北归

东坡①还至庾岭②上，少憩村店。有一老翁出，问从者曰：“宜为谁？”曰：“苏尚书③。”翁曰：“是苏子瞻欤？”曰：“是也。”乃前揖坡曰：“我闻人害公者百端，今日北归，是天佑善人也。”东坡笑而谢之，因题一诗于壁间云：“鹤骨霜髯心已灰④，青松夹道手亲栽。问翁大庾岭头住，曾见南迁几个回？”（宋？曾敏行《独醒杂志》）

[注释]（D东坡：苏东坡，即苏轼。曾贬官至惠州、儋州（今广东、海南一带）。②庾岭：即大庾岭。在今江西、广东交界处。③苏尚书：苏轼曾官至礼部尚书，故称苏尚书。④鹤骨霜髯（rán）心已灰：这是苏轼形容自己的形态与心情。

Motivation is "the driving force within individuals that impels them to action." And goals are the sought-after results (1) motivated behavior.
Motivation can be either positive or negative (2) direction. We may feel a driving force toward some object or condition, (3) a driving force away from some object or condition. For example, a person may be impelled toward a restaurant to fulfill a need, hunger, and away (4) an airplane to fulfill a need of safety. Some psychologists refer to positive drives (5) needs, wants or desires, (6) negative drives as fears or aversions (7) , though negative and positive motivational forces seem to differ dramatically (8) terms of physical and sometimes emotional activity, they are basically similar in (9) they both serve to initiate and sustain human behavior. (10) this reason, researchers often refer (11) both kinds of drives or motives as needs, wants and desires.
Goals, (12) , can be either positive or negative. A positive goal is one toward (13) behavior is directed and it is often referred to as an approach object. A negative goal is (14) from which behavior is directed away and it is sometimes referred to as an avoidance object. Since both approach and avoidance goals can be considered objectives of motivated behavior, most researchers refer to (15) types simply as goals. Consider this example. A middle-aged woman may wish to remain (16) attractive as possible. Her positive goal is to appear desirable, and (17) she may use a perfume advertised to make her irresistible. A negative goal may be to prevent her skin (18) aging, and therefore she may buy and use face creams. (19) the former case, she uses perfume to help her achieve her positive goal -- attractiveness; in the (20) case, she uses face creams to help avoid a negative goal -- wrinkled skin.
