Having unnecessary meetings can cost you a lot of time.  Not only does it cost you time, but it costs the time of the other participants of the meeting.

To solve this problem, make sure you only schedule meetings when it's necessary to do so.  And only invite people that absolutely have to be there.  That way, you'll save the time of those who don't have to be at the meeting.

Meetings can often drag out and end up wasting a lot of time.  You might end up socializing too much.  The meeting might go off track to a discussion about last week's baseball game.  So be sure to have an agenda to make sure the meeting is on track.  There also needs to be someone to make sure the meeting sticks to the agenda.  Whenever the meeting goes off track, that person will bring it back to the agenda.

But it's easy for meetings to go overtime.  That ends up wasting everyone's time at the meeting.  So it's important to have a time limit or a time that the meeting will end.  That way, it keeps the meeting from going overtime.  And people can get back to work afterwards.

To minimize your meetings, how many meetings should you have?  One meeting a week is usually a good number to shoot for.  Any more meetings than that may be unnecessary.  Less than once a week might be too little.  But in general, try to go for the number of meetings that are just enough for your needs and no more.
