Borrowing from Stephen R. Covey's (7 Habits of Highly Effective People) concept of how we make withdrawals and deposits into our personal integrity account whenever we either break or keep the promises to ourselves; and makes withdrawals and deposits into our emotional (relationshps) account when we break or keep promises to the people we interact with (as just one example of withdrawals and deposit); so do we make deposits and withdrawals into our fitness/health accounts based on the things we do or fail to do in our daily lives.
Also, how proper strength training not only builds muscles but also build character.
