“In a society that profits from your self-doubt, liking yourself is a rebellious act. Loving yourself is anything but naive. If you don’t become your best friend, who else will? If you don’t convey confidence in what you do, don’t expect others to trust you. We are what we believe we are. When you embrace your true identity, there’s no room for self-doubt. The shadow of self-doubt might show up unexpected. It’s up to you to move from darkness to light.”
I am not sure why self-doubt seems to live in a vacuum. Self-doubt, like self-confidence needs a context. I had self-doubt about becoming a father until I had kids. I had self-doubt when I got my first job. I had self-doubt when I went on my first field trip. I have had self-doubt many many times, but I faced them all and converted my self-doubt into self-confidence.
Perhaps fear of the unknown would be a better paradigm. Instead of focusing on self, focus on what circumstances creates this fear and find strategies to overcome it. If the fear is really deep, soliciting the help of friends and family would be advantageous. If it turns out to be phobic, a counselor or therapist may need to intervene. Doubting oneself is a good thing because it keeps one cautious in the beginning. It focuses on learning the ropes slowly and prevents one from jumping to the wrong conclusions unnecessarily.
Ignorance is the fuel for self-doubt. Experience is its only remedy. And self-confidence is its only reward.
