Don't shake someone's ground

na buddhibhedaṃ janayedajñānāṃ karmasaṅgināmjoṣayetsarvakarmāṇi vidvānyuktaḥ samācaran

The wise should not unsettle those attached to action. Working steadily themselves, they should encourage all good work.

What it means

Krishna gives practical advice. Don't confuse people who are attached to their work by telling them it doesn't matter. Buddhi-bheda, splitting their understanding, can leave them with neither old motivation nor new wisdom. Better to work well yourself and encourage others in their work.

The story

Arjuna may one day become wise. Krishna warns him not to become the kind of sage who discourages others. A clumsy teaching of detachment could make a young warrior simply give up. Wisdom should lift people, not knock them down.

In your life

Picture a new hire who's excited about their first big project, and a jaded colleague telling them none of it matters. Don't be that colleague. Encourage people's effort, and let your example do the teaching.
