Lyric discussion by up4grabs 

His friends advise him:

"Find yourself a girl, and settle down Live a simple life in a quiet town"

He did, but now it's:

"Steady as she goes (steady as she goes) Steady as she goes (steady as she goes) So steady as she goes"

He must remain composed as she goes on and on yapping and bossing him around. (I guess that would be the typical male point of view.)

OR

"Steady as she goes (steady as she goes) Steady as she goes (steady as she goes) So steady as she goes"

He's must keep it cool and not give in and go after her, thus risking the marriage his friends are convincing him to pursue. (If he is afraid of the commitment.)

"Well here we go again, you've found yourself a friend that knows you well But no matter what you do, you'll always feel as though you tripped and fell"

He becomes friends with a girl, but as always, ends up falling for her.

"When you have completed what you thought you had to do And your blood's depleted to the point of stable glue Then you'll get along"

Obviously, the pair can get along only when one of them yields in favor of the other, in this case HE's the one complying.
