Do you ever lose your concentration or become easily distracted?

Are you easily distracted? Do you find it hard to concentrate on tasks at hand?

I often lose my concentration and sometimes outright forget what I was in the middle of doing. It’s very frustrating when this happens especially when i’m working on my site. I find this happens a lot more when I have a headache. If I have a headache or feel dizzy I tend not to do anything so i don’t lose concentration mid-task and end up screwing something up.

What about you? Do you lose concentration or are you easily distracted at times?
