Mahasi Sayadaw Noting Method (mostly as taught by Yuttadhammo Bhikku): Help with mindfulness during daily activities? I'm having immense troubles with maintaining mindfulness during the day. Is it really as simple as noting whatever is prominent? Do I just need to stick with it?

Generally, I'm confused as to what exactly to note / not note. For example....

When I'm walking around at my job, I see people whom I have a desire for to like me. Others, I don't care so much, and sometimes there is some disdain for these people. 

In these times I feel like if I focus on and note the walking or movements of the body or tension in the body, I'm neglecting my attachment / aversion to the person I'm seeing, the unwholesome thoughts and feelings that have arisen, etc.- and vise versa! When I note the thoughts/feelings/tension etc, I feel like maybe I'm just making a stink out of stuff and causing more stress than is beneficial, but maybe I'm wrong. 

These times sometimes seem like an endless stream of physical tension / mental anguish / restlessness, and it causes a lot of dysfunction and anxiety in me, and sometimes I just give up and ditch mindfulness until my next formal session, or at least until I get away from these people. 

I'll admit that I've seemed to have had success with noting in these moments one time, the other day. Anxiety left me alone for a bit and I was able to joke around with some of these people who I tend to so desperately want to like me. I felt free of that desperate want for them to like me for a bit. That's certainly a step up from feeling paralyzed by anxiety, even if it is mostly just worldly pleasure. 

But I still have so much doubt and hopelessness built up that I really would love to hear some other's experiences in these situations, hopefully someone who also practices Mahasi Sayadaw's noting method. Again I'd like to ask, because maybe I just need a kick in the pants, do I just need to stick with it? I've watched a video on how Yuttadhammo dealt with anxiety and he basically said "stick with it even though your body might be freaking out and it might even be obvious to those around you, and maybe you'll be having a terrible time. Eventually you'll get a handle on it". I'm very much paraphrasing. :)

Thanks in advance.
I'm not familiar with Yuttadhammo Bhikku, but from a short look at his teaching I believe the key is that one should not be noting things; one should be noting mind movements. For instance, looking at the discussion of vipassana on his website, he says this:


  The Four Foundations of Mindfulness are:
  
  
  Body: Noting the body while prostrating, walking, and sitting.
  Feelings: Noting pain as “pain”, happiness as “happy” and calm as
  “calm”.
  Mind: Noting thoughts about past or future – both good and bad – as
     “thinking”.
  Dhammas: Noting hindrances as:
  
  
  “liking”
  “disliking”
  “drowsiness”
  “distraction”
  “doubt”
  
  


Now, this is within the context of meditation, but notice the focus. He doesn't want you to notice (say) that you like the color of the head monk's robe; he wants you to notice that a feeling of 'liking' has arisen in you, without necessarily paying attention to the external focus of that feeling. You notice it arise, you notice it persist, you notice it fade...

Translate this to walking through your office: If you encounter a person whom you wish would like you, notice the desire to be liked rise in you. If you encounter a person you dislike, notice the disdain rise. If you have a moment of anxiety, notice the anxiety. You don't need to do anything other than notice. When you bring these large movements of the mind into conscious focus they will start to shift and dissolve of their own accord. Then you do it with more subtle mind-movements, and even more subtle ones, until your mind is perfectly calm and still.

Try to keep in mind that the people and things that you encounter do not cause the movements of your mind. You make them, when you form attachments to what these people and things represent to you, and those attachments drag through your mind like a rope pulled through water. Unless you notice the movement, you won't be able to see the attachment.
