It’s late on a Friday afternoon and you are feeling spent. You feel like you’re fried crispier than a piece of bacon on a greasy hot griddle. You are mentally and emotionally drained after a long week of work, yet you still have one important task you need to finish before you can start a weekend of much-needed rest and relaxation.

Your boss is expecting the updated project budget and you know she’s not going to be happy when she sees it. Despite your best efforts in managing the team, the project is over budget and it looks like the situation is going to get worse before it gets better.

As you review the budget for what seems like the millionth time, you realize you could fudge the numbers a bit and shift some of the costs from the Implementation Team to the Design Team and it would make the overall budget look better. Who’s going to know? Besides, the Design Team consistently runs over budget and you usually take the heat for their mistakes. You could make this budget change, save yourself an hour’s work, start your weekend now, and avoid the wrath of your boss on Monday morning.

What do you do?

Well, according to research, you are likely setting yourself up to cheat and be dishonest. In this study, Dan Ariely (who has written about this subject in several of his books) and a team of researchers illustrated the connection between our level of self-control, resource depletion (mental/emotional), and the likelihood to cheat.

The gist of the experiments showed that participants who engaged in activities that depleted their self-control resources were more likely to cheat on subsequent tasks (rewarding themselves more than they actually earned), and even more alarming, were more likely to place themselves in tempting situations that resulted in them cheating even more!

So how does this apply to us as leaders? Well, anyone who has experience leading groups of people knows that leadership can be an energy draining and resource depleting activity. As a leader, nothing is more important than your integrity. All it takes is one moment of weakness to compromise your ethics and you’ve torpedoed your whole career.

Here are three practical, commonsense ways to avoid this dilemma:

1. Be intentional about recharging your batteries – This research, along with our practical experience, shows we can make bad decisions when our self-control resources are low. It stands to reason that the best way to prevent this from happening is to make sure our self-control resources stay high. We have to keep our batteries charged. All the things your mom told you growing up apply: get enough sleep, eat right, exercise, find a hobby, and engage in activities that nourish you mentally, physically, emotionally, and spiritually.

I can hear some of you saying, “Easy for you to say, Randy, but you don’t understand my work environment. I’m expected to work 70-80+ hours a week, stay connected to work 24/7, and do whatever it takes to get the job done.” If that’s your situation then I have empathy for you. It must be miserable and I can see how easy it is to feel trapped, especially if you’re beholden to the large paycheck that’s usually used as an incentive to get people in those kinds of jobs. But remember, you have choices. They may be tough choices, like scaling back your lifestyle, seeking a new job, or changing careers, but you do have choices. It will likely take time and require some tough decisions, but don’t fool yourself by thinking there’s no way out. You have a choice.

2. Don’t make decisions when you’re tired or hangry – It’s important to know yourself well enough that you can tell when your self-control resources are running low. For many of us, self-control goes out the window when we’re tired or “hangry” (hungry + angry = hangry). This is certainly true for me personally. I can see a clear pattern of making not-so-good decisions when I’ve been in this kind of state.

If this is true for you as well, then we both know what to do: don’t make significant decisions when we’re in this vulnerable state. If at all possible, delay making the decision until you’ve had a chance to recharge your batteries. There is wisdom in the old adage of “needing to sleep on it” when faced with a significant decision. We think more clearly and are in a better state of mind when our self-control resources are on full rather than empty.

3. Avoid tempting situations, especially when you’re running on empty – It seems too obvious to even mention but it has to be called out: avoid tempting situations at all costs, especially if your self-control resources are running low. The frightening thing about this particular research study is that people in a resource depleted state were even more likely to expose themselves to tempting situations. It’s as if our “temptation radar” is degraded when our self-control resources are low; we don’t fully recognize the danger of the situation. Using the project budgeting example above, it would be better to let that task go for the day and revisit it on Monday morning, than settle for the quick, easy, and unethical strategy of fudging the numbers…even if it means getting chewed out by your boss for being late with the report. There is never a right time to do the wrong thing, and it’s never the right time to make an important decision when you’re tired, exhausted, or feeling mentally or emotionally drained.

Leaders are givers. We give people our time, energy, support, guidance, coaching, and many other things that can leave us feeling like we’re running on empty. When our tanks are empty we expose ourselves to making decisions that can damage our integrity and erode the trust of our followers. We need to keep our own tanks full, not only so we can give to others, but also to protect us from ourselves.
