One of the easiest, most powerful ways I've changed my daily life is by using the @momentumdash plugin for Chrome. It shows you your to-do list right on your homepage, so whenever you get sidetracked, you get a reminder when you pull up a new tab about what you're supposed to focus on. Then it asks you, what's your focus for today? and you get to set your intention and keep being reminded of it. The beautiful imagery & the quotes are all a plus, also.
