No matter what your profession or your personal life is like, we all have tasks or projects we've been falling behind. Something always comes up to get in the way.
Time blocking, as in making an appointment for yourself on your calendar can help. If you doubt me, I challenge you to prove me wrong with just a half hour of your time.
Either professionally or at home; think of a project or task that you've been meaning to complete and need to complete, but haven't yet. Now find an open half hour on your calendar and block it off to focus solely on that task.
When the time comes, turn off your smartphone, turn off your email, mute your desk phone, and focus all of your attention for that half hour on the task at hand. If you work in an office environment, reserve an open conference room for yourself if one's available.
You will be amazed at the amount of work you can get done in that mere half hour.
Now just think what you can do if you can block off a half hour or an hour every day.
