We, too, are often tempted from what we know we need to do by friends and family who have the best of intentions. While we probably shouldn't call them "Satan," we need to recognize when these distractions are keeping us from being the best possible versions of ourselves. This doesn't mean that we should completely ignore friends and family, or other diversions, just that we should not use them as an excuse to not accomplish that which we know must be done.
As a practiced procrastinator, I know that I struggle with this problem regularly. Just look at how much writing I've completed this summer (not counting blogs and some minor school-preparation, the total is three paragraphs). I have had a great summer even if I have little to show for it. I'm not going to beat myself up over what I haven't done, but I need to put my failings behind me and move forward.
