" For example, somebody who is addicted to pornography might be doing well to avoid it, but then come across an arousing picture on social media that triggers their addictive habit. Being self-aware in that moment means that as soon as the person feels their response to the image, they recognize that feeding that response at all will make it harder to remain disciplined. Instead of mindlessly staying on social media and looking at more pictures until the urge becomes stronger, having self-awareness helps to cut it off at a manageable place. You may not be able to catch yourself in the act, but being self-aware means at least catching yourself earlier and earlier in the process, as opposed to sitting for an hour on social media and then wondering where the time went.
