Don't suppress your intense compulsion to write just because it got you into trouble a few times... It is a gift. Manage it.

1. Always send your stuff to a few friends before you hit the publish button.

2. Don't write inappropriate personal confessions. Invent a character, have them live the inappropriateness and call it fiction.

Edit: 3. Revise the shiz out of your work until it is good enough that others can enjoy reading it.
