Depends upon how fast did your left side of the brain develop. Globaly watching....12-15 year olds make crap. Reason, immaturity. There are some exceptions of course, like Xnod, but other than him everything I've seen so far is crap. Now we have a category of late teen and early college years 17-20 in which the quality of videos is mixed up. There are really good creators, decent creators and creators that produce crap. And we have a category of matured people who make videos (20 and above). Look at the age of the creators that are most respected here: AD, Koop, Wonka, VegettoEX, Vlad, Kusoyaro etc. Those are all mature people, college students or even married people (maybe

).
Even looking new creators I get the feeling that older ones give out better results and advance faster. If we compare AD & SSJBrolli who registered in the same year and were completely the same in their n00b glory what results do we get? AD was in his 20's when he first joined and Brolli was 12 years old. In 3 years Brolli hasn't improved even a toe when it's up to creating and as for AD....you all know.
This is all of course a personal way of seeing things which are based upon personal experience. It differs from person to person.
