1. Build competence gradually. We all want to hit home runs but it's a bad idea to set tasks that are simply too daunting.
2. Don't help too much. Smart people cherish autonomy, you shouldn't rush in to solve problems your employees are still working on.
3. Be social. Devote the first half hour of the two-hour weekly meeting to 'non-science' topics.
4. Make assignments personal. The hardest part about studying science is deciding what to focus on.
