Self-doubt is that part of the soul that is able to taste the bitter in life as well as the sweet. It is open to a side of life that a sunny disposition must ignore in order to carry on smiling. It is less interested in pretense and more aware of the suffering entailed in daily living. It is realistic about the balance of suffering and happiness, but because of this realism is willing to be thankful for whatever genuine happiness is possible. It celebrates the melancholy nature of aloneness, but because of its refusal to shirk aloneness knows the worth of a real relationship.

I have self-doubt. I have insecurity. I have fear of failure. I have nights when I show up at the arena and I'm like, 'My back hurts, my feet hurt, my knees hurt. I don't have it. I just want to chill.' We all have self-doubt. You don't deny it, but you also don't capitulate to it. You embrace it.

Self-doubt is so insidious that it not only renders us stuck in our lives, but it also actually weakens our ability to dream about what living unleashed would look like.

We all have tremendous potential, and we all are blessed with gifts. Yet, the one thing that holds all of us back is some degree of self-doubt. It is not so much the lack of technical information that holds us back, but more the lack of self-confidence. Some are more affected than others.

There are individuals who are haunted by self-doubt, whose attitude to life is negative and distrustful, or who exist in a state of confusion about what they are and what they can become. … Unlike physical deprivation or obvious social injustice, evils like these strike at the very roots of human life. When men can no longer picture themselves as worthy of existing, it scarcely matters whether they have the means of existing.

I think self-doubt is probably what keeps me going, keeps me pushing myself, because I never think I’m at the right level. The minute I think I’m at that level, I’ll probably not get the job done. The way my head works is I always think I’m not as good and have to work harder.

"If you find yourself asking yourself (and your friends), "Am I really a writer? Am I really an artist?" chances are you are. The counterfeit innovator is wildly self-confident. The real one is scared to death."

Our doubts about ourselves cannot be banished except by working at that which is the one and only thing we know we ought to do. Other people's assertions cannot silence the howling dirge within us. It is our talents rusting unused within us that secrete the poison of self-doubt into our bloodstream.

worth noting the distinction between doubting the work and doubting yourself. An example of doubting the work would be, “I don’t know if my song is as good as it can be.” Doubting yourself might sound like, “I can’t write a good song.” These statements are worlds apart, both in accuracy and in impact on the nervous system. Doubting yourself can lead to a sense of hopelessness, of not being inherently fit to take on the task at hand. All or nothing thinking is a nonstarter. However, doubting the quality of your work might, at times, help to improve it. You can doubt your way to excellence. If you have an imperfect version of a work you really love, you may find that when it finally seems perfect, you don’t love it in the same way. This is a sign the imperfect version was actually the one. The work is not about perfection.

Self-doubt, which is the artist's bitterest enemy.

The problem is, some of us have either convinced ourselves that we are not creative, or are yet to find our way. Confidence in our own creativity can wane. Which is bad. Confidence is crucial. In my experience artists, like a lot of us, fear being “found out.” But somehow they manage to summon up enough self-belief to overcome the self-doubt, which enables them to back their creativity. The Beatles were just a bunch of young lads with time on their hands who found the confidence to persuade themselves and then the world that they were musicians.

Anyone who expects to create, be it as a scientist or artist, scholar or writer, needs self-confidence, even bravado. How else can one dare to imagine understanding what no one else has understood, discovering what no one else has discovered? Where does this confidence come from? Fortunately, every young person is blessed with some of it. It is part of human character.

The worst enemy to creativity is self-doubt.
