1. Lack of motivation. A talent is irrelevant if a person is not motivated to use it. Motivation may be external (for example, social approval) or internal (satisfaction from a job well-done, for instance). External sources tend to be transient, while internal sources tend to produce more consistent performance.

2. Lack of impulse control. Habitual impulsiveness gets in the way of optimal performance. Some people do not bring their full intellectual resources to bear on a problem but go with the first solution that pops into their heads.

3. Lack of perseverance and perseveration. Some people give up too easily, while others are unable to stop even when the quest will clearly be fruitless.

4. Using the wrong abilities. People may not be using the right abilities for the tasks in which they are engaged.

5. Inability to translate thought into action. Some people seem buried in thought. They have good ideas but rarely seem able to do anything about them.

6. Lack of product orientation. Some people seem more concerned about the process than the result of activity.

7. Inability to complete tasks. For some people nothing ever draws to a close. Perhaps it’s fear of what they would do next or fear of becoming hopelessly enmeshed in detail.

8. Failure to initiate. Still others are unwilling or unable to initiate a project. It may be indecision or fear of commitment.

9. Fear of failure. People may not reach peak performance because they avoid the really important challenges in life.

10. Procrastination. Some people are unable to act without pressure. They may also look for little things to do in order to put off the big ones.

13. Excessive dependency. Some people expect others to do for them what they ought to be doing themselves. (more…)
