Mindfulness in Everyday Activity
First, congratulations on your year of practice. Sometimes we overlook the most basic principles of our practice, as such I am referring to the first noble truth: there is suffering. Note that it is not stated, "I suffer". By being stated this way it can be understood that suffering is not, "yours" or "mine". As opposed to viewing these experiences as, "I am embarrassed" or "I am feeling awkward" reflect upon these moments as, "there is embarrassment" or "there is fear". Know they are not yours but emotions that result from a particular experience. Also, bear in mind that as you reflect upon this experience you are being mindful and in the moment (meditating). Being mindful does not in itself guarantee happiness. Mindfulness combined with skillfulness will move you toward your goal. These principles are found in the Eightfold Noble path. Try noting your experience. Saying to yourself for example, "fear" or "embarrassed" as you would during formal or seated meditation, allowing for the physical response to dissipate.  

"To let go of suffering, we have to admit it into consciousness. But the admission in Buddhist meditation is not from a position of: "I am suffering" but rather, "There is the presence of suffering" because we are not trying to identify with the problem but simply acknowledge that there is one." - Ajahn Sumedho
