Goals should be attainable, flexible, and what else?

Goals that are described as attainable, flexible, and measurable ensure that they are not only achievable but also quantifiable, allowing for progress tracking. Measurable goals provide clear criteria for evaluating success, which is essential in maintaining motivation and focus. By defining specific metrics or indicators, individuals can assess their advancement towards the goal, determine what works, and make necessary adjustments along the way. This characteristic enhances accountability and creates a structured approach to achieving objectives.

While the other attributes, such as being specific, timely, and realistic, are important in goal setting, focusing on measurement is key for growth, reflection, and adaptation, which are essential components of effective goal achievement.
