I tend to zone out- a lot. I've been doing this all my life and my boss talked to me about this particular habit of mine today, asking me if I had ADD. He told me that I reminded him of someone close to him that has it and honestly I think I might. 

I'm 20 right now and haven't really had huge issues in my life from zoning out, more just teachers asking me what they'd just said because they noticed I was staring through them at the wall. Sadly, my zoning out is starting to effect me at my job.

Those of you diagnosed with ADD, what was the give away that you had it?
