between comfort zone and anxiety fear zone. there is an achievement zone. that makes you feel like you have done something new and accomplished something. then you invest more and then the fear, low confidence and anxiety kick in. I experience this everytime I try to learn something new. like as simple as bottle flip challenge. first it's exciting. a few lucky shots boosts your morale. you try to make more consistent shot and feel like your skill is actually degrading the more your practice. then little by little you make improvement in a micro scale.
