> If, for example, you would build a house, you might not feel confident that the roof will resist rain and snow. The good way to handle such fears is to learn about state-of-the-art roof construction. The bad way to handle such fears is to take a mindfulness class where you learn how to feel confidence in the face of the unknown. To me, this "good way" isn't a way to build confidence. If you dig the roof building subject, you will probably stumble upon different good building solutions. Worst, you could find out the subject is controversial. In the first case, you need confidence to pick a solution. In the second case, you need even more confidence to pick a solution. To me, confidence builds up when you face situations like this, pick a solution amongst all these options even though it might not be optimal or even though it's disputed, and either get rewarded with a positive outcome or with a lesson clear enough that you know it will help you do better next time. To generalize further, to me confidence builds up when you are satisfied about the outcome you got when you battled challenges that matter to you, or satisfied about your behavior during the battle itself.
