Was 2013 a bad year for your credibility rating? If you’re honest, you might have to admit to a slip-up or two. (Maybe not on par with the most notorious celebrities and politicians, but bad enough!) Perhaps you were late more times than you would like to admit, you missed several deadlines, you told a few white lies to clients, and somehow you turned into one of the office’s top gossips. There may even have been a couple of bigger transgressions: like promising to increase your sales by 50 percent and then coming in way under the mark (tanking your department in the eyes of the higher-ups).

Is it too late to redeem yourself?

Probably not, say Julie Miller and Brian Bedford, coauthors of “Culture Without Accountability—WTF? What’s the Fix?” Chances are you haven’t hit the credibility point of no return just yet—but salvaging your image requires making a herculean effort to be more accountable in 2014.

Here, Miller and Bedford share a tip to help you repair your credibility after it has taken a hit:

Credibility Repair #2: Always do what you say you’ll do. Doesn’t it make you crazy when someone says, “I’ll get back to you tomorrow on that,” and days later you haven’t heard a word? Or, “We’ll make sure you get it on Monday,” and nothing happens?

“Don’t be that person,” instructs Miller. “If you make a commitment to do something, move heaven and earth to do it, or if you can’t—because circumstances beyond your control have impacted you—let people know immediately, with a plan to fix it. You’ll find that generally others are pretty understanding when you give them legitimate advance notice.”
