According to the Bible, the little it speaks about Heaven shows it to be an organized place, as well as glorious since Jehovah God Himself. In short, it's perfect...for those that belong there. The scriptures state that only a limited number of people are going to Heaven, and that these ones are chosen by Jehovah and Jesus, people don't choose for themselves. (Revelation 14:1-4) So what about the rest of the righteous/good people that don't go to Heaven? The scriptures point out that they will live upon the Earth, with evil people no longer in existence. (Proverbs 2:21 & 22; Psalms 37:10, 11, 28 & 29) Also, everything that makes life miserable now (besides bad people...) will be done away with. (Revelation 21:4) So basically, it's not surprising for people to feel like they don't belong in/want to go to Heaven, since the majority of people will end up on Earth in the future.
