I'm told if I get one more traffic ticket, I'll get my license taken away.

Of course, I'll do my best to try not to get a ticket, but, in reality, sooner or later I will get a ticket, because if tickets were that easy to avoid I wouldn't have gotten the other ones in the first place.

Just like I'll try to do my best not to get in trouble at work, or I'll do my best to turn in all of my schoolwork in on time and do it perfectly, or I'll do my best never to say or do anything stupid

Face it, my best isn't good enough. I screw up even the simplest tasks. My best is failing, and hearing over and over again how I'm a failure and why can't I be more like the people who do are good, productive adults?
