Just ran across this today... even if you don't consider yourself a Introvert, this is a great read for anyone, including those of us with ADHD when it comes to distractions and forms of communication.

I agree almost 99% with the author on this, as I am an introvert as well.

Article discusses thoughts, theories and approaches. Very LONG and covers different topics throughout, so if you can't focus on it, bookmark and go back later. :)
