Insecurity : the state of being subject to danger or injury.
The first step is recognizing the lie. Yes, you know enough to know how much you still don’t know. Yes, you feel like one more book or one more conference will finally give you enough information to no longer feel insecure. The truth is, you know more than most right now. The truth is, you are not in danger. That is the lie. You have a lot to give, no matter where you are in your journey.
Don’t freeze up. Keep learning, recognize your limitations, and add value to everything you touch. The world needs more developers like you.
