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.

Third, we need to keep our goals consistent. That is, when setting goals, we need to be sure that none of our goals contradict or undermine each other. The easiest way to do this is to have an overarching plan. Working through my Business Planning Makeover, for instance, will show you how to create a framework of business goals by creating an action plan to move your business ahead.
2. Don’t get too caught up in ‘big’ things. A lot of the time when we think about goals, we think they need to be really big – and this can be overwhelming. Change how you think about goals. A goal can be anything you want to do or achieve – big, small or completely random, such as learning how to tell a great story at a party, or taking part in a fun-run dressed as a stormtrooper.
Some coaches recommend establishing specific, measurable, achievable, relevant, and time-bounded (SMART) objectives, but not all researchers agree that these SMART criteria are necessary.[6] The SMART framework does not include goal difficulty as a criterion; in the goal-setting theory of Locke and Latham, it is recommended to choose goals within the 90th percentile of difficulty, based on the average prior performance of those that have performed the task.[7][3]
