You really made salient points. More often than not, we sing our goals to everyone, and eventually bury it at procrastination grave. It's quite hard a task to keep to one self but I think will pay off. I would want to think there might be exceptions if the goal requires some professional expertise one may not possess, in a case you may need to speak to a professional. Thank you for the post. I stand to be corrected.
