You're comments reminded me of something I posted on my Facebook page. I didn't say it at the time, but it was also about dealing with a lack of concentration:

"Be more efficient.
My dad quit fishing because it became frustrating for him to tie the knots. I now know what he went through. My eyes aren't as good and my fingers not as nimble as they used to be.
From changing a spark plug to tying your shoes, everything you do, every physical action- do with forethought, care, and above all- purpose. At first people will call you slow or methodical but over time, your speed and performance will pick up. It's your life, you get to choose the pace. And it helps to put your glasses on..."

I also got tired of misplacing my keys and my lighters (smoke free for a year now). I learned to focus intently now on where I place them. My keys get shoved deep in my right pocket when not on the key rack.

I don't know what you're experiencing but it's not mindfulness. Mindfulness is not involuntary and ironically, takes a conscious effort.
