As with most things, a balance of doubt is required. A little doubt in our minds in consideration of our capabilities is a good thing. Too much doubt can become oppressive.
If we first pause to consider to learn a best way, we wouldn’t simply rush in to act. Doubt presents the opportunity we generally require to process and learn before we would act.
If the balance of doubt is overwhelmingly negative, we often won’t approach to act at all. When full of doubt, the mind is closed to learning and any guidance we might be receptive to so that we would proceed.
We are never to be too sure of ourselves and never to be locked up with the fear of failure. Discern for yourself a balance to proactively open the mind to learning and leading a course for yourself within the doubts you may have. When in doubt, consider the opinion and guidance of others.
