Natural ability would be nice and maybe makes things just a bit simpler, I do think some with natural ability tend to focus only on the things they find natural, where I like to say I am more "Technically Creative" since it is all just the culmination of observing, processing and spewing out new information.

The schools seem to skip the processing part and instead focus on just storing and regurgitation then we all go into the world just regurgitating everything we learn but never letting it into the mix and make us a bit sick to get mixed with other things then spewing out a hot mess of creativity.

As we all find ways to be a little bit more creative in our daily lives, you are correct that a support structure can improve your growth unless that is me then you might get a bit stinted, constructive criticism is as much required as a snap out of it already gut punch, ok maybe we never require the gut punch but no one is perfect.
