Rigid people who stick to the old traditions will summarily fail to strike out in new ways. Conformity is the enemy of creativity. Afraid of any kind of disorder or ambiguity, they cling to a sterile symmetry, thus closing off many creative avenues. Egoistically tied to a certain pattern, he or she will do it his or her way rather than try any new, possibly superior solution. Instead of a rich emotional life, he has settled for safe boredom.
Spontaneity is mistrusted, and even seen as dangerous.
For such people, sensitivity is underdeveloped and there is poor contact with both one's self and the environment. They're just not up to reaching a higher creative level. And they lack interest in achieving this. So the first step is to point out these creative blocks and show how a different perspective may lead to useful changes. Shifting over from the negative hindrances to creative output, we can then approach the problem from the positive side.
