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.[12] 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 well-being factor happiness (subjective well-being) and goal integrity is associated with the well-being factor meaning (psychology).[13] 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.[14][15][16]
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.[17] It looks at the likelihood and impact of goal achievement based on the type of goal and meaning of the goal to the individual.[citation needed] Different types of goals impact both goal achievement and the sense of subjective well-being brought about by achieving the goal. The model breaks down factors that promote, first, striving to achieve a goal, then achieving a goal, and then the factors that connect goal achievement to changes in subjective well-being.
Assess why you're slipping: are you not sticking to your plan, or is your timeline unrealistic? If it's the latter, adjust your plan to something more reasonable. If it's the former, work on dedicating yourself to sticking to your target. Sometimes our plans are thwarted by outside influences, about which there's not much you can do; simply reorient yourself and continue onward. Keep in mind that failure is a part of progress.

The Great Observatories All-sky LIRG Survey (GOALS), is combining imaging and spectroscopic data from NASA's Spitzer, Hubble, Chandra and GALEX space-borne observatories in a comprehensive study of over 200 of the most luminous infrared-selected galaxies in the local Universe. The sample consists of approximately 180 Luminous Infrared Galaxies (LIRGs), which are systems with total infrared emission brighter than 1011 L☉ and less than 1012 L☉, as well as over 20 Ultra-Luminous Infrared Galaxies (ULIRGs) with luminosity of 1012 L☉ or greater. The objects are a complete subset of the IRAS Revised Bright Galaxy Sample (RBGS), which comprises 629 extragalactic objects with 60-micron flux densities above 5.24 Jy and Galactic latitude above five degrees. The RBGS objects, all with redshifts, z < 0.088, are the brightest 60-micron sources in the extragalactic sky. The LIRGs and ULIRGs targeted in GOALS span the full range of nuclear spectral types (type-1 and type-2 AGN, LINERs, and starbursts) and interaction stages (major mergers, minor mergers, and isolated galaxies). They provide an unbiased picture of the processes responsible for enhanced infrared emission in the local Universe, and are excellent analogs for comparisons with infrared and sub-millimeter selected galaxies at high-redshift.

A positive relationship between goals and performance depends on several factors. First, the goal must be considered important and the individual must be committed. Participative goal setting can help increase performance, but participation itself does not directly improve performance.[3] Self-efficacy also enhances goal commitment.[5] For goals to be effective, people need feedback that details their progress in relation to their goal.[3]
