First question: what makes me think i am going to heaven ? After reading the Bible 43 years total now,concluded that it is through faith in Jesus Christ that i will be there. Jesus did it all. Actually we do not need 43 years of reading just true faith in Jesus Christ.
Now we are ready for what do i or you expect in heaven ? God will be there the angels (the good ones) and all the saved people will be there. I expect to see what are written in the Bible will be there. No more sorrow, sickness or pain.
No more rush hours, no more locks, no more deadlines, no more hunger or thirst, no more bills, no sins, no more break downs, no scams or thieves, no trash...
You may say, could it be boring there ? Maybe after billion or trillion of years over there, maybe but i do not think so.
