"Ooh, that looks interesting!"
We've become a society in pursuit of instant gratification. We can't wait. We want to know. We need to know. Right now! Unfortunately, most new information isn't urgent and, perhaps, not even important. However, we haven't trained our brains to handle the second step: to ask, "Is this urgent?"
To overcome distractibility, you need to develop a two-step brain pattern:
1) Evaluate the incoming information.
2) Shift back to the present if the information isn't urgent, or jump off and focus on the new information if you judge it to be a high priority.
A helpful way to do this is to rate the urgency and importance of each new message or input. Give it a rating of 1-10. Anything seven and over demands immediate attention. Anything four or below can probably be ignored for the time being.
Remember that technology can help us: Most cell phones now ask us if we want to listen to a new voicemail or read a new text now or later. With e-mail you have the option to click on the pop-up announcing a new message or not.
