From personal experience and from what I have seen in clients and others, it is easy to lose your workout focus. Here is one pointer for you: Don't skip Friday and Monday workouts! These are days that are easy to skip because we're thinking about the weekend on Fridays and getting over the weekend on Mondays. Add in the days that will probably be skipped on Saturday and Sunday, and you have not worked out for 4 days! Sometimes, this turns into weeks, months and years. One good way to prevent this is to NEVER skip workouts on both Friday and Monday, and try not to go more than two days without working out. If you must skip a workout, some good substitutes are pick-up basketball/football games, mowing the lawn/yardwork, household cleaning, walking the dog, walking to the store, shopping/walking at the mall, dancing and swimming. STAY ACTIVE!
