Personal Discipline
Personal discipline goes a long way in spiritual progress. Personal discipline shows an inner discipline—that you are balanced, that you don’t put your needs before that of others. It shows itself in courtesy: you give way to others, let them sit first. You will let others eat first, don’t rush.
