To me twelve months is a long, long time for someone to suddenly change their mind He was in and out, now it's just too late But I won't lose one night of sleep Worryin' about what was meant to be His leavin' is just a reason to celebrate Chorus I'm on a mission, I got a cause I'm gonna hit every rockin' little honky-tonk bar and the way I'm thinkin', it ought to be against the law Gonna see what kind of trouble I can find I'm on a head-on collision with a real good time I'm on a mission, and it's all about forgettin' tonight Forty-hour week and I'm out the door'Seems like all I'm workin' for Is that time when I can finally just cut loose I got a few good friends and they're waitin' to go just gimme some time to change my clothes 'Til Monday mornin', there ain't nothin' I gotta do (Chorus) Ain't worried 'bout a five-day no-sleep business-week No-escape workin'-girl blues Yeah, I'm just doin' what any other Modern day American woman might do (Chorus) I'm on a mission and it's all about forgettin' tonight I'm on a mission Ira Dean / Kim Tribble / David Lee Murphy '2002 WB Music Corp./Mojo Dean Publishing/Beechtree Publishing (all rights obo Mojo Dean Publishing and Beechtree Publishing adm. by WB Music Corp.) /Old Desperado Music/N2D Publishing Co.
