I guess I have pretty much always been a bit of a scatter-brained "dabbler" in many things... always jumping from one thing to another.

But yes, I do find it helpful for my concentration to "turn off the faucet" so to speak... too much stimulation makes it that much harder for me to concentrate. In fact, in order to write, I often end up taking my laptop to a different room of the house where the Wifi doesn't quite reach, so I avoid distractions.
