Self awareness or mindfulness is something we can teach ourselves, but it doesn't hurt to get advice or read up on it.  So many people I fear go through life with little or no self-examination, or when they do examine themselves it is against irrational or even harmful standards, and full of rationalizations to enable them to excuse themselves or to continue doing and believing things that are not rationally based, but instead come from indoctrination or desires.  Religions are a major offender here, in particular when they encourage irrational beliefs based on their authority or tradition or some divine claim or another.
