We learn from the scriptures that in the hereafter there are three kingdoms of glory where all serve Jesus Christ in eternity and one kingdom not of glory where Satan reigns supreme. The following is my understanding of the differences between these four kingdoms:
The Celestial Kingdom is governed by our Heavenly Father, and all who are there are there because they want to be there and to do what Celestial beings do: They minister to others, blessing them in the name of and by the power of Jesus Christ with the magnitude of the light of the sun.
The Terrestrial Kingdom is governed by Jesus Christ, and all who are there serve Christ. They were the honorable mean and women of the earth during their mortality, carefully keeping all of the Ten Commandments. They also serve others in the name of and by the power of Jesus Christ with the magnitude of the light of the moon.
The Telestial Kingdom is governed by the Holy Ghost, and all who are there serve others in the name and power of Jesus Christ, with magnitude of the light of the stars. These are they who broke the Ten Commandments in their mortality but afterward repented of having done so.
The Kingdom of no glory is presided over by Satan. These are they who delight in and do only hurt and destroy others, having learned to do those things in mortality by seeking the destruction of others using the power and influence of Satan.
Everyone in a kingdom of glory is happy and is satisfied with their situation. Everyone in the kingdom not of glory is unhappy and is never satisfied with their situation and accomplishments.
And everyone in every kingdom is exactly where they themselves chose to be. (See D&C 76)
