If you want to be a great leader, be aware that your team members need to feel that:

1. They know what they should be doing
2. They have the tools (training, parts, equipment, etc.) to get those things done
3. They have an opportunity to do things they are good at.
4. Their work is appreciated (and praised)
5. Their leaders care about them as individuals
6. Their work matters to the team
7. Their ideas/wishes are heard
8. They have opportunities to learn and grow
9. That they have a good friend on the team

Asking people about their interests and skills helps with some of the above and nurtures the relationships you will depend on during build season; it shows you care about the person as an individual. It also helps you get people working on what they do best so you can leverage everyone's strengths.
