If you've ever had a coworker actively interfere with your productivity, try to make you look bad, steal your ideas, or give you false information, you've been the victim of undermining.

One of the signs of a bad coworker is a pattern of persistent undermining - intentionally hindering a colleague's success, reputation, or relationships.

The opposite of an underminer is a supporter. When colleagues are supportive, they go out of their way to be givers rather than takers, working to enhance our productivity, make us look good, share ideas, and provide timely help.

If you want your children to bring original ideas into the world, you need to let them pursue their passions, not yours.

Procrastination gives you time to consider divergent ideas, to think in nonlinear ways, to make unexpected leaps.

If an organization values innovation, you can assume it's safe to speak up with new ideas, leaders will listen, and your voice matters.
