Advice? WHY ME?

I really have been in a funk for a while now. My mind has been out of control with a very large number of small tasks that need to be taken care of. I am not sure why I have been so inefficient when it comes to taking care of them. I truly need to spend one week and just take care of everything. I spent the evening alone debating whether to be productive or just relax and enjoy the peace and quiet. I decided to watch a back episode of Nip/Tuck, possibly one of the most thought provoking shows I've seen in a while. I just finished the second season and thoroughy enjoyed it. So often the plots parallel my inner challenges with myself as a person.
While I am usually bombarded with compliments and positive reinforcements as to who I am, I virtually finish every night thinking I could be doing so much more in this world. I have my priorities, and I don't seem to stray too far from them, but I know I need to expand my horizons a bit. One of my favorite customers put it best with, " If you want the guacamole, then you have to dip your chips." I thank her for that, and in due time I will break out of my shell, and live life a little more. This leads me to talk about a couple of themes I've been bombarded with lately.
Having been in the same area for a while I have watched many relationships grow and fail at the same time. Recently an ex employee told me "IT IS OVER" with her husband, not a day goes by that I don't hear a man or woman complain excessively about there spouse, often with offers or words that would immediately end the marriage. Somehow I have ended up with the title of the go to guy to vent about how crappy the womans husband is. I haven't quite figured out if I offer great advice, if I somehow remind them how good they really do have it after realizing their husband could be sitting on a stool working at a convenience store talking to other woman all day, or perhaps I am suppose to play the middle man and creatively relay the message in a better way to their husband when he comes by later for his beer. As with every conversation I have at the window, I like to assume or at least pretend that my opinion truly does count. I could not imagine it if nobady gave a damn about what I had to say. One last dumb note pertaining to me giving relationship advice. This is coming from someone who failed at his own marriage. However, today would have been 15 years, so at least it is longer than most out there.
