What is heaven like? If one doesn't know the answer to this question, it is easy to see why they wouldn't be motivated to work toward getting there. Some think that in heaven we do nothing but sing praises to God for eternity. While there is merit in that thought, it isn't the full description.
While the physical description of heaven is fascinating, more important is the description of the people that live there. The people is what makes heaven heavenly. Those who live with God are living like God. They have learned to live in a way that brings joy and happiness to themselves and their posterity.
