Most folks feel like imposters at least some of the time. That is especially the case when we’re thrust into new experiences and feel out of our depth.

The way out, I’ve observed, is not to push the feeling away or attempt to resist it in some way. Instead, folks who deal with these feelings well remind themselves that it is just another manifestation of fear.

And, the way out of fear is to take action with the knowledge that there’s no getting rid of fear.

Action, it turns out, is simply our way of acknowledging that there are things more important than fear.

My study of Stoicism was partially driven initially by this sense of imposter’s syndrome. I grabbed on to the ending of this article by Massimo Pigliucci:

So take those failures, and those moments of doubt, as additional
opportunities to exercise virtue and become a better human being:

“The art of life is more like the wrestler’s art than the
dancer’s, in respect of this, that it should stand ready and firm to
meet onsets that are sudden and unexpected.” (Meditations, VII.61)
