Goals

Everyone has goals. Many people do not reach their goals for lack of planning. These three sets of goals should be developed: lifetime, intermediate and short term.

Lifetime goals should be written out. These goals should be clear and reasonable. For instance, the goal to win a research prize is clear and measurable. Other lifetime goals might include publishing a certain number of influential books or articles, earning a departmental chairmanship at a major university, successfully competing for a grant from the National Science Foundation or securing a consultantship with a big corporation.

Intermediate goals relate to outcomes during the next few years. For the beginning doctoral student, intermediate goals may include completion of course work and preparation of a doctoral research proposal. Like lifetime goals, these are measurable and clearly stated.

Short-term goals involve outcomes expected during the next 12 months. These goals are more performance oriented, and they help with achievement of intermediate goals. Examples of short-term goals are earning an A in a course, learning how to program a computer or performing an experiment.
