That certainly is one approach to take. My own is to acknowledge the inner child and try to work with my first fascination with science fiction. I have tried to build on its idea content and narrative drive rather than to discard them.
Scientists do their best work when they are in their early years. Writers' skills don't necessarily decay; if they can keep their interests and hopes alive (like Jack Williamson), their experience allows them greater depths to explore.
I could give you some names of Workshop participants who are as good as many who are being published but haven't had the right editor recognize their merit or have not been adequately published.
