Take three cords or strings of various, pleasing pastel colors perhaps pink, red, yellow, or green and braid them tightly together.

Firmly tie a knot near one end of the braid, thinking of your need for happiness.

Next, tie another knot, and another, until you have tied seven knots. Wear or carry the cord with you until you find happiness.

After that, keep the cord in a safe place, or give to one of the elements (for example burn and scatter the ashes in a stream, or bury the cord in the earth where it will be undisturbed.)
