Sometimes being scared about not being able to “hack it” ties into us not knowing what is good enough.
What is it you are trying to accomplish? What are you really wanting as an end result? What are the finer details regarding the idea of success you’ve conjured in your mind’s eye, and who do you need to become to even achieve such a thing?
We get anxious when we crave control, and what we want to control most is what people think of us.
Take the step. Risk being judged. The inability to please everyone does NOT mean you aren’t “worthy,” it means that you tried something worthwhile.
What being able to “hack it” really means is a willingness to get started, along with being excited about learning how to lay a firm foundation with the bricks others will inevitably throw at you. Experiment, learn, evolve. Those are the ingredients of improvement.
