The challenging goals challenge our current abilities and to achieve these goals requires more creativity and effort than other goals. The challenging goal has two great advantages for individual and organizations.
The first advantage, the challenging goal creates our motivation and the second advantage that unlocks our potential.
Motivation
When you set challenging goals it brings out the enthusiasm from your within. Edwin Locke that put forward the Goal-setting theory of motivation, said: Goals should be realistic and challenging. This gives a feeling of pride and triumph when he or she attains his or her goals, and it sets him or her up for attainment of next goal. The more challenging the goal, the greater is the reward generally and the more is the passion for achieving it.
Different studies show that two types of goals don't create enthusiasm and motivation in us. First category is the simple goals that access to them is easy. These goals create reluctance and crazy. The second category is the difficult goals that access to them is very difficult , this group is cause of hopelessness. Both categories have a common feature that is not associated with hopeful state. Because hope and fear are inseparable. The easy goal hasn't fear and the difficult goal hasn't hope. Rumi believe although fear and hope are opposite in appearance, but both have a duty that is to create motivation. He said “fear and hope like board in sea will be used by sailor for reaching to his lover.”
Actualizing potentials
The challenging goals push you beyond the thresholds of mediocrity. A challenging goal helps you to develop your talents and ability and you become a new person in the process. This is a form of personal development. The most important your need is actualizing potential. And a challenging goal setting is the best response to this need. The truth is that you are a potential genius and these challenges unlock your inner genius. Many challenges and obstacles remain on the way of your goal, when you overcome any obstacle, a part of your talent will reveal. Arnold Toynbee, British historian who examined the rise and fall of 26 civilizations in the course of human history, and he concluded that they rose by responding successfully to challenges under the leadership of creative minorities composed of elite leaders. Civilizations declined when their leaders stopped responding creatively. Challenging goals are not only the main factor for creating civilizations, but also are the key factor to unlocking your full potential.
