It’s tempting to want our feelings to be absolute: provable and fungible and tangible. But confidence varies from person to person and from day to day. Confidence is a feeling, and feelings are difficult to measure and control. Reassurance is futile because it seeks to shore up a feeling, and in any given moment, it might or might not do the job. We don’t have to be victim to our feelings. They don’t have to arrive or leave of their own accord. We can choose to take actions that will generate the feelings we need.
