My biggest problem is my family as gentle as I can put it (wife and 3 kids) which require a lot of attention so it's easy to say "eh that website can wait my family needs x,y,z." I'm no master but I've gotten better at this by leaving my home for 1-2hrs a day and going to my local coffee shop to work. My mind knows now by this point that when I'm there I'm there to work and that's it, has worked wonders for me.
