Do you think Christians long for heaven as they ought to?

No. In providence, Christians are prompted to take heed of the brevity of life from time to time, for example an illness or the death of a loved one. For a moment, you realize that we could be gone tomorrow. However, we tend to push that aside. We tend to think and plan as though we will be here at least until we are a hundred.

It is a balance because we’re not meant to dislike this life. We are meant to take part in this life, to do our duty as Christians and be a salting influence within a fallen society. We have the assurance as Christians that we are citizens of another world and that this is not our home. So, we should seek the world which is to come whose Builder and Maker is God.
