Maybe the key to our adult life is to be more childlike. This doesn't mean to give up being an adult, to give up all our responsibilities but it means to be more lighter,
to enjoy life more, to learn how to live carefree. It isn't really easy sometimes, but it is worth the process. Sometimes we also have to learn to take things easier. Don't be too serious and hard on yourself.
Let your inner child have fun and enjoy life. You decide.
