5. In-house accountability partner.
There have been days, many days, I have had to drag my wife out of bed. There have been days where she has gotten me up, and out of a mood from a bad day to get a workout in. When she wants to sleep in and miss, I am there to get her going. When I want to shut it down early and miss, she is there to get me going. You encourage one another and work together to stay with it.
