Your lifestyle has gone on for too long. It is time for you to toe the line - get a wife, a job, some kids, and be miserable just like everyone else. Many mistakenly think the phrase is "tow the line", thus obscuring the meaning. This term comes from military line-ups for inspection. Soldiers are expected to line up, that is put their toes on a line, and submit to the inspection.
