smudged with ashes

Lent is less than 24 hours away. Tomorrow I'd go to church and get my forehead smudged with ashes from last year's palms or so we're told. As a Christian, I'm supposed to give up something sinful and/or wrong in my life for the rest of my life especially for the next 40 days. I have no idea what I'll give up this time around, but I must confess that I couldn't give up what I tried last year. Does this make me a bad Christian or a bad person? Well someone upstairs will sure decide.
