Learn to notice change. Learn to notice the small things. Learn to notice when you change positions from seated to standing or vise versa. Learn to notice when your breathe goes from inhale to exhale. Notice when you go from sleep to awake. Notice when you go from hungry to satisfied. Bring more awareness by noticing these shifts within yourself.
When you notice these changes you start to notice change is natural. The universe and you are built for change and adaptation. It is your natural progression to change for the better. You do not need an ah-ha moment the change has already happened and it is up to you to recognize you have already changed.
