People like to create when they can earn recognition for their ideas.
When a good idea surfaces, the creator's immediate superiors should show prompt appreciation. When you give they say that you get a lot in return. Even if you had a bit part in earning accolades for a project well done, pass the recognition on to someone else. Let the other person bask in the glory. Many people will know you were there too, but you will reap more benefits by letting someone else reap the recognition.
