What is required for effective change is continuity of sincere effort to release and let go of inefficient thought patterns from the past.
Some people change when they see the light, others when they feel the heat.
The moment you have in your heart this extraordinary thing called love and feel the depth, the delight, the ecstacy of it, you will discover that for you the world is transformed. Nothing is easy to the unwilling. If you don't like something, change it. If you can't change it, change your attitude. Such 'knowledge' is so thoroughly a part of our worldview that it simply would not occur to most people to question it.
