Not necessarily.  It takes a long time to dispel the fear and most of the time fear wins.  Confidence is not great at all..and it is much more relaxing and reassuring to stick with the same routine.
If you do work for charities then that is good that you do that but don't try to ''force'' people to feel that they have to go all out, there are a lot of problems that one has to ''face'' before generally being able to dispel the fear and succeed.
