One of the morals, or life lessons, one takes from "The Wizard of Oz" is for people to discover their own paths in life, as is stated by Belief Net. This is directly related to the yellow brick road that takes Dorothy to Oz, her goal. It was there in front of Dorothy all along. She just needed to look a little bit harder.
Another moral given by Belief Net is for people not to hide their true selves, such as when the wizard hid behind the screen and pretended to be the Great and Powerful Oz. The people who matter most in a person's life will love him or her regardless, so it is best to be authentic.
People need to look for the power within themselves to find the answers to life's questions, according to Belief Net. This part comes from the part in the movie where Dorothy misses the hot air balloon that is supposed to take her back to Kansas. Glinda the Good Witch tells her she has the power within herself to get back home. All she has to do is say "There's no place like home" and click her ruby red slipper heels three times.
The next idea from Belief Net states that running away is not the best option. Dorothy tried to run away when her neighbor attempted to take her dog Toto away. Instead of being swept up in a tornado and landing in Munchkin Land, if Dorothy had simply faced her problems with a little help from friends and family, she would have figured out the best way to handle the situation.
