Uncle Ben said it best: “with great power comes great responsibility.” This should be the phrase by which every leader and marketer lives.

Marketing and leadership are two fields primarily focused on influence. Leaders focus their efforts on influencing what work gets done and on what companies place emphasis; marketers focus on what products get made, what gets purchased, and what changes are made in our culture.

With great influence also comes great responsibility. Leaders and marketers have in their hands the power to persuade others towards things that are either helpful or harmful.

Who gets to decide which is which? Technically, it’s the follower, the consumer, or the customer. But we are all human–we know before a customer tells us whether or not our product or idea will harm her.

If you lead others, if you sell, or if you persuade, please take your responsibility–the power you have over other people–seriously.

Don’t take advantage.
