I saw this line recently (“If you keep doin’ what you’re doin’, you’ll keep gettin’ what you’re gettin’.”) and I chuckled because of how often I experience this with my clients.

I'll hear things from my clients like "Our data is really bad; I don't trust it at all," or "Every time we run this report we get a different result." But when I ask what they've done to address the problem, the answer is "Not much. We just know it's a problem."

The best time to start cleaning up your data was long ago. The second best time to start is today.

When you run across things like bad data or "broken" reports, take the time, at that moment, to try and figure out a solution to the problem.

CHANGE what you're doing, so you'll get better results next time.

Because if you keep doin’ what you’re doin’, you’ll keep gettin’ what you’re gettin’.
