Difficulties of Unlearning
People find relearning more difficult than learning from basics.
Not only is it necessary to gain the new idea, but to forget the old thought and this may prove a major problem.
Where several ideas form a new way of proceeding with a particular method of operating, the old way of carrying out the process may reappear in the person's thinking.
A possible result may be the person is not able, for varying lengths of time, to use either the old or the new method effectively.
Effective practice or a period of careful thought, before attempting the renewed skill for real, is the answer.
Again, acceptance and a desire for a change of thinking and practice is quite essential, as is time and patience.
