A wise kid will look within and keep it as a lifelong habit.
Of course there is no such thing as an inner child but it makes you better to play make believe.
A healthy sense of mindfulness and a good practice of meditation will go a long ways.
Believe deeply in living a healthy life in all your affairs and do no harm.
There is no one way, but many.
Live, love and learn.
