"Enough with this 'mistakes were made' hoo-ha. If you started on the wrong foot, be accountable for it. And don't be so hard on yourself. Nobody's perfect. Afterward, you'll find many burdens lifted from your shoulders."
Passing blame and not being accountable is so not my thing. Being too hard on myself though? Hah, just ask anybody that knows me.
My shoulders could use a lifting these days.
