Perhaps you should try some spelling variations:
"motivational speakers" » "motivational sparc", "motivational makeovers", "motivational aspects"
"motivational states" » "motivational systems", "motivation state", "motivational system", "amotivational states", "motivation states", "motivational scales"
"motivational state" » "amotivational state", "motivation state", "motivational scale"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("motivational state") OR ((("motivational speakers") OR ("motivational states")))).
• Removing quotes may allow a broader search: (( motivational state ) or ((( motivational speakers ) or ( motivational states )))).
• Adding a wildcard symbol may retrieve word variants: (("motivational state") or ((("motivational speakers") or ("motivational states"))))*.
