Choose when to have a meeting to get a decision and when to just make one and then let everyone know via email. Not everything requires a gathering.

Choose wisely who to invite to meetings. Leave out the disruptors who usally add nothing but difficulty. Don’t include them because you feel compelled to. Include them because they can contribute to the end result.

Stay on subject. If something else crops up, set another time to discuss it. It is your meeting. Claim it and control it.
