Distance isn't usually the issue. The book has been on your shelf for two years — owned, four feet away, unread.
Within reach and actually reached are separated by something other than difficulty. Attention, mostly. A thing has to become today's thing, and plenty of goals never get a today.
Give one of yours an appointment. Not a plan — an appointment, a specific hour with nothing else in it. Reachable things stay unreached mainly because nobody ever scheduled the reaching.
