As an adult, you can be whomever you want to be as well. It's not too late to become who you want to be. It will take work, just like it took my parents to make my various costumes. The end result however is priceless.
2. Creativity allows for growth.
Your Halloween costume shows your creative side. You put your energy into your creation and become that character, through your unique creativity.
In adult world, you should use creativity every day. Make every day your masterpiece. Even if you feel your job is dull, and doesn't allow for creativity, I beg to differ. You can create anything in your life.
3. Courage to approach complete strangers.
Kids will go up to houses and ask people to give them candy. Think about this for a moment. Going up to complete strangers, and asking them for something, without giving them anything in return.
Try doing that in Times Square, and you'll get your ass beat, or at minimum some quite colorful (colourful) response. I wish it wasn't that way. We don't communicate enough with people. Twitter, Instagram, Facebook, Snapchat is a form of communication, but it's not real, physical communication.
I hope you get all your favorite candy tonight.
