Common sense should inform us that as long as you have someone else to blame for your shortcomings, whatever they are, chances are you are not going to repair them.

I suggest it's not a matter of having someone else to blame for your problems. There's always someone else to blame (rightly or wrongly).

Blaming others is the mark of immaturity and weakness of character.

People with integrity bear responsibility for their actions.
