Imposing your will on others will cause a revolt. Although you are the most powerful person in the group, that won't last long if you act like a tyrant. Instead of getting angry at everyone's uncooperative behaviour, call a meeting. Invite everyone to speak freely about what they want and need. Promise there won't be any repercussions for harsh criticism. If you treat people with care and compassion, they'll work hard to satisfy your demands. The key is setting goals that benefit everyone, not just you.
