Accept the RIGHT thoughts. You get what you accept. This is straightforward. If you want to have an ambitious character, you will have to learn how to train your mind to persevere through obstacles. Once a thought is taken captive, that thoughts begin to create your life.
You must get rid of toxic thoughts. Toxic thoughts must be removed from your mind. You must get rid of the old way of thinking if you want to live the life of someone different. Your mind is the product of what you had allowed.
You must plant positive thoughts. Inspired by someone? Great! Use the opportunity to awaken yourself into greater potential. Your belief system is the key to your success or failure in life. When you challenge your belief system you are able to break through the barriers standing between you and the life of your dreams. You are able to create a new paradigm.
You must renew your mind daily. For me, the key to unlocking the power of the mind has been this. Well, you see.. whatever you do not maintenance will inevitably malfunction. The mind that is neglected will produce a defeated life. You must renew your mind regularly and fill it with the kinds of thoughts that propel momentum in your life. If you do not like what you are producing you need to change what you are planting.
