There is a definite nature of ‘doubt’.
Doubt is always about something that is positive; you doubt someone’s honesty, you never doubt her dishonesty.
Doubt arises on action not inaction.
Doubt arises on knowledge not on ignorance.
Doubt challenges wisdom, not foolishness.
Doubt, with suitable struggle and inquiry, brings clarity and affirmation
This awareness is essential – to doubt the ‘right things/people or situations‘.
