I suggest you read some Randy Alcorn or Tom Wright, because your concept of the Christian hope is completely off base. 'Heaven', for a start, is an unhelpful term because most people think of a disembodied 'bliss' (strumming harps on cloud nine, or an eternal church service). That is about as Christian as eating a side of bacon is Jewish or Muslim.
The Christian hope, for a start, is an eternal *embodied* existence on *this* earth. This earth (like believers in their bodily resurrection) will be transformed so that sin, suffering, pain and death are completely wiped away. Yes, we will worship God forever, but that does not mean we'll always be bowing down before him, or sitting in an eternal church service. I agree, that would be boring. God is the source of all true joy, comfort, fun, and love. Imagine that forever *at full volume*. Why would God, who is all-knowing, all-powerful, and morally perfect, come up with such a pathetic eternal existence for those who love him as you have imagined?
Moreover, most of the best things about life now will be there (without sin, which will make them so much better): friends, sport, music, culture, dance, books, animals, trees, forests, science, technology, art, conversation, meaningful and enjoyable work. And of course, people. Life will *never* be boring. Any good thing from now that isn't there won't be needed, and won't be missed. You want an eternal adventure? That's what you'll get, an far more than you can possibly imagine, if you forsake sin and trust in God in the flesh: Jesus Christ (who died for our sins according to the Scriptures, was buried, and rose again the third day according to the Scriptures). Think I'm making this up? Read Ephesians 2:4-10:
"But God, being rich in mercy, because of the great love with which he loved us, even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—and raised us up with him and seated us with him in the heavenly places in Christ Jesus, so that in the coming ages he might show the immeasurable riches of his grace in kindness toward us in Christ Jesus. For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them."
Hell, on the other hand, will not only be full of shame and contempt, it will also be incurably lonely and boring. You won't have any meaningful interaction with anybody, ever. There are no parties, no debauchery, no drugs, no money, sex or power. Nothing of value, except yourself. However, since you've declared God of no value, you've declared yourself of no value as well. We only derive our true value from God. Who wants to spend their eternity in shame, loneliness, and boredom?
