reach a destination city within three hours; an individual might try to reach financial goals such as saving for retirement or saving for a purchase. Managing goals can give returns in all areas of personal life. Knowing precisely what one wants to achieve makes clear what to concentrate and improve on, and often can help one subconsciously prioritize on that goal. However, successful goal adjustment (goal disengagement and goal re-engagement capacities) is also a part of leading a healthy life. Goal setting and planning ("goal work") promotes long-term vision, intermediate mission and short-term motivation. It focuses intention, desire, acquisition of knowledge, and helps to organize resources. Efficient goal work includes recognizing and resolving all guilt, inner conflict or limiting belief that might cause one to sabotage one's efforts. By setting clearly-defined goals, one can subsequently measure and take pride in the accomplishment of those goals. One can see progress in what might have seemed a long, perhaps difficult, grind. Achieving personal goals Achieving complex and difficult goals requires focus, long-term diligence, and effort (see Goal pursuit). Success in any field requires forgoing excuses and justifications for poor performance or lack of adequate planning; in short, success requires emotional maturity. The measure of belief that people have in their ability to achieve a personal goal also affects that achievement. Long-term achievements rely on short-term achievements. Emotional control over the small moments of the single day can make a big difference in the long term. Personal goal achievement and happiness There has been a lot of research conducted looking at the link between achieving desired goals, changes to self-efficacy and integrity and ultimately changes to subjective well-being. Goal efficacy refers to how likely an individual is to succeed in achieving their goal. Goal integrity refers to how consistent one's goals are with core aspects of the self. Research has shown that a focus on goal efficacy is associated with happiness, a factor of well-being, and goal integrity is associated with meaning (psychology), another factor of well-being. Multiple studies have shown the link between achieving long-term goals and changes in subjective well-being; most research shows that achieving goals that hold personal meaning to an individual increases feelings of subjective well-being. Self-concordance model The self-concordance model is a model that looks at the sequence of steps that occur from the commencement of a goal to attaining that goal. It looks at the likelihood and
