First things first, if you have been secretly worried that you may be incompetent that’s not it. That thought is a brain error! Repeat brain error!
It’s not your fault that you keep starting and stopping or get into full-blown freeze mode when you try new or hard things, it’s your brain’s fault.
Your brain is well-intentioned. Your brain's wired to protect you from danger. It doesn't want you to try new or hard things. It thinks you could die. It's programmed to protect you from being eaten by the next wild animal that comes around. It tries to conserve your energy at every turn in case of an emergency. But last time I looked no wild animal was out to get us anymore. Unless you are vacationing somewhere exotic and get lost from the crowd. This used to be a good thing because it kept our species going and allowed us to survive. But now it doesn’t serve us.
