In fact scribbling and producing doodles does enhance motor skills, hand to eye co÷rdination and lets out (and develops) one's creativity. In the end what it actually does is improve quality and improve the overal skillset. Drawing instructors will tell you so and some will even go so far by telling you it is one of the best ways to improve your drawing skills.
Your personal opinion isnt factual but you bring it to the table like so which is dangerous towards any aspiring artist seeking advice or feedback.
Perhaps you should do a little research before making any statement like that, just like I did (google is your friend).
As insulting as you're statements were towards me, I will strive to keep this peaceful. I have climbed up the talent ladder. I was above your level when I was 7 years old. I would still be there if I scribbled. Scribbling might help with production but not with skilled production.
