Go outside. Be somewhere where there are trees releasing their leaves. As you feel a breeze come, inhale. Take a deep, full breath that fills you all the way to your toes.
As you see and hear the leaves dropping and moving around you, imagine one thing that no longer serves you.
Exhale and imagine that it has gone with the leaves into the wind.
Allow Mother Gaia (Earth) energy to take it away from you for it to be reborn as something useful.
You could also incorporate this into a meditation.
