Those who attain self-concordant goals reap greater well-being benefits from their attainment. Attainment-to-well-being effects are mediated by need satisfaction, i.e., daily activity-based experiences of autonomy, competence, and relatedness that accumulate during the period of striving. The model is shown to provide a satisfactory fit to 3 longitudinal data sets and to be independent of the effects of self-efficacy, implementation intentions, avoidance framing, and life skills.[19]
Step 5: Initiate actions that support your feelings of abundance and success. Here, the key word is actions. I've been calling this acting as if or thinking from the end and acting that way. Put your body into a gear that pushes you toward abundance and feeling successful. Act on those passionate emotions as if the abundance and success you seek is already here. Speak to strangers with passion in your voice. Answer the telephone in an inspired way. Do a job interview from the place of confidence and joy. Read the books that mysteriously show up, and pay close attention to conversation that seem to indicate you're being called to something new.
To make sure that your goal is motivating, write down why it's valuable and important to you. Ask yourself, "If I were to share my goal with others, what would I tell them to convince them it was a worthwhile goal?" You can use this motivating value statement to help you if you start to doubt yourself or lose confidence in your ability to actually make the goal happen.
Welcome to the club! Great question. There are any number of reasons why we may be unable to achieve a goal by the deadline. Your instincts are on the mark. When you find yourself in a situation where you are unable to achieve your goal by the initial date you set for yourself, revisit the goal. If it is a big goal, break the goal down into smaller goals and set deadlines that are realistic to achieve.
Goal displacement occurs when the original goals of an entity or organization are replaced over time by different goals. In some instances, this creates problems, because the new goals may exceed the capacity of the mechanisms put in place to meet the original goals. New goals adopted by an organization may also increasingly become focused on internal concerns, such as establishing and enforcing structures for reducing common employee disputes.[24] In some cases, the original goals of the organization become displaced in part by repeating behaviors that become traditional within the organization. For example, a company that manufactures widgets may decide to do seek good publicity by putting on a fundraising drive for a popular charity, or having a tent at a local county fair. If the fundraising drive or county fair tent is successful, the company may choose to make this an annual tradition, and may eventually involve more and more employees and resources in the new goal of raising the most charitable funds, or having the best county fair tent. In some cases, goals are displaced because the initial problem is resolved or the initial goal becomes impossible to pursue. A famous example is the March of Dimes, which began as an organization to fund the fight against polio, but once that disease was effectively brought under control by the polio vaccine, transitioned to being an organization for combating birth defects.[24]
Amazing post, and very timely! I agree 100% with "create your "big picture" of what you want to do with your life (or over, say, the next 10 years)" - so many people (me included) just don't do this and then struggle with staying on track. I found that by using SMART goals and especially by identifying my emotional attachment (the big reason WHY) behind my goals, I could start to actually achieve them. Now I am hooked!

Step 7: Monitor your emotions as a guidance system for your connection to the universal mind of intention. Strong emotions such as passion and bliss are indications that you're connected to Spirit, or inspired, if you will. When you're inspired, you activate dormant forces, and the abundance you seek in any form comes streaming into your life. When you're experiencing low-energy emotions of rage, anger, hatred, anxiety, despair, and the like, that's a clue that while your desires may be strong, they're completely out of sync with the field of intention. Remind yourself in these moments that you want to feel good, and see if you can activate a thought that supports your feeling good.
Step 2: Affirm: I attract success and abundance into my life because that is who I am. This puts you into vibratory harmony with your Source. Your goal is to eliminate any distance between what you desire and that from which you pull it into your life. Abundance and success aren't out there waiting to show up for you. You are already it, and the Source can only provide you with what it is, and, consequently, what you are already.
Step 4: Use your present moments to activate thoughts that are in harmony with the seven faces of intention [creativity, kindness, love, beauty, expansion, abundance, and peaceful receptivity]. The key phrase here is present moments. Notice right now, in this moment, if you're thinking that it's hopeless at this stage of your life to change the thoughts that comprise your belief system. Do you defeat yourself with thoughts of having had such a long life practicing affirmations of scarcity and creating resistance to your success and abundance that you don't have enough time left to counterbalance the thoughts that comprise your belief system?
Keep your motivation high by setting goals that are attainable and relevant to you and your life. Making sure your goals are meaningful, realistic and timely will help you stay encouraged and give you an incentive to press forward. The best goals are those that connect with your intrinsic motivation; in other words, they are things you feel internally compelled to pursue.

Whilst the ideas represented by the acronym SMART are indeed broadly supported by goal theory (e.g. Locke, 1996), and the acronym SMART may well be useful in some instances in coaching practice, I think that the widespread belief that goals are synonymous with SMART action plans has done much to stifle the development of a more sophisticated understanding and use of goal theory within in the coaching community, and this point has important implications for coaching research, teaching and practice.
