Matthew 6:20,21

Lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal.  For where your treasure is, there your heart will be also.  

How do we store up treasures in heaven?  One way is to not concentrate on accumulating things here on earth.  It is ok to have possessions, but as long as they are not our focus.  Next, we need to focus on what is important to God.  We are meant to love people on earth and give into the development of the kingdom here.  God is intended to be the focus and our treasure.
