"Paradise" as defined by Jehovah's Witnesses is: Preaching to people for 1,000 years.
Yes! After you give up all personal pursuits or any joy in this "old system of things" for a life of preaching an unpopular message to your neighbors you are rewarded by being spared at Armageddon. In addition to being spared, you get to preach that same message, but for an additional 1,000 years.
There will be no time for personal pursuits. You will have even less personal freedom as you won't even get to decide were you will live while conducting this 1,000 year preaching work. When you are not preaching you will be working tirelessly with stoneage technology to provide food and shelter for yourself.
Why waste your life pursuing anything in this temporary life and run the danger of losing out on this grand future that awaits us?
