Because low self-esteem is sometimes caused by our own internal dialogue in the way of negative messages, it really does make sense to nourish our mind with positive messages in order to increase our self-esteem. By giving ourselves positive affirmations we can improve our self-esteem and well being.
Giving ourselves positive affirmations can sometimes be a block for some people not only because they find it difficult to take on board and accept affirmations but they don't really know what to say to themselves or know how to word the affirmations for maximum effect.
