I do use my breathing as an anchor for presence and relaxing when I am out and about. Although the lucid realization should rather be viewed as the moment you realize that you haven't been focused, but ideally you should always strive towards staying in consciousness and not have to experience the lucid realization because you are always lucid. So instead of viewing it as a memory test view it as a conscious striving lifestyle. ;)
When you see objective results and your life change the presence and consciousness brings to your mood and life in general, you are going to want to exist in that state more often.
We are always falling back to our default mood of thoughts and emotions, so make sure that it's a state of mind that you enjoy. Just like an usually angry person easily can get angry, an usually present person easily can get present.
I know this because I used to be very anxious and used to overthink the small things, now when I am usually more present I am more like a laughing buddha and smile to the small things, very easily in a happy mood. :content:
And when you are happy and not distracted by thoughts and emotions, there can finally be awareness.
Peace! :meditate:
