Showing my true, real self is hard. Bullied, teased, made fun of for who you really were is hard to come from. That's why people put up walls, barriers, masks, to hide behind. They're afraid that people will do it again, just like the people before.
This quote means that we don't go with e flow all the time. If we are open-minded and just let the world take us where it wants to go. We often try to control what the world wants us to do. We should just keep an open mind and let the wind take us where it wants to go and let the world carry out its intentions for us. Follow me!
