If you feel a sense of accomplishment for doing the work that someone you lead should be doing, then you may be addicted to firefighting work that gives you a sense of accomplishment. It’s more likely, however, that you are really avoiding the difficult decisions and the difficult work that you are responsible for as the leader.
Leaders are stewards of the future. If you aren’t working on the future because you are spending the majority of your time on today, then you are putting that future in doubt.
If you aren’t working on your biggest strategic opportunities and your most difficult systemic challenges, then those opportunities are at risk, and the bottlenecks created by systemic problems will mire everyone down in day-to-day firefighting.
As a leader, you are responsible for doing the work of the leader first and foremost. It cannot take a backseat to work that someone else can and should be doing.
