A paradise for everyone and all. A place where any needs had are met, including the needs we deem imperfect. Without unwanted consequence. Maybe there are no more needs in heaven. It's the perfect state of being, one that anyone would do anything for to achieve.
If you place all the things you desire in a line from what you desire a little to what you desire most and imagine the effort you would put in to obtain it, this would be bigger than all else in the world. A glimmer of hope of achieving this state, of realising what it entails, would absorb you. It would be your everything. The only thing stopping you right now is doubt that it's in reach. And a lack of understanding of what it would be like.
Whenever we talk about free will or our hopes and dreams, it's about getting a little closer to that state of being. Life is about moving there, in that direction. Much like seeds growing into trees, you are made to find a way there. In that sense, all that is life is ultimately on the same team with the same goal in mind.
The only thing in life we cannot have enough of, is betterment. And if life gets enough time and chances, I think life will find a way to be ever closer to a state of heaven. Which doesn't mean that heaven doesn't already exist. It very well could. Even scientifically speaking, if you believe in theories like many worlds theory or alternate dimensions in general.
