Encouraging ideas - a management training course

How can you encourage ideas?  By saying to yourself, “No idea’s either totally useless or totally perfect.  I’ll make a habit of looking hard for what’s good in an idea before  being critical.  This will encourage ideas, and also help me keep a more open mind.”
 

You can develop and practise encouraging ideas by always looking for what's good in an idea before being critical on our highly acclaimed London UK management training course, “Skills with People”.
 

But how can you be sure this training in encouraging people and their ideas is for you?
