Search, then ask
Step one should not be to create a Discussion, first search, you may find answers already documented in Discussions, Documents, Blogs or others. And before posting anywhere, you may want to search for the best Community to post to.
Win-win through feedback
When others help you on a Discussion you created, flag their reply as Helpful or Correct, it will help others in this community to find valuable resources.
Share your successes
You have valuable resources to share ? Create a Document, describe goal and content, insert a screenshot, attach files. You'll be amazed at how others will leverage your content
