There are two very different schools of thought on the way the affirmed message will make things happen. However, both agree using affirmations works.
1. Some believe that using daily positive affirmations will change your thought processes and subconsciously help you achieve your goals. They believe that you'll be more aware of opportunities for success when you have a successful belief system.
2. Others believe you're sending the message to the Universe and accept the good results as a message back from the Great Spirit to them. They use the power of belief in a force bigger than themselves, much like the power of prayer.
It doesn't matter who is right. What matters is the fact that writing affirmations can help change your life.
