The Talmud in Ethics of the Fathers chapter 4 shares both of these seemingly contradictory comments:
A single moment of repentance and of good deeds in this world is greater than all of the World to Come.
A single moment of bliss in the World to Come is greater than all of this world.
Wait a second… If one moment of good deeds in this world is so much greater than the next world, why would the bliss of the next world be so much greater than this world??
Right now you are in the world of accomplishment and mission. After the soul departs the body it embraces a very blissful existence but one that is devoid of mission.
Heaven can be compared to a lovely retirement home, where nothing is expected and everything is provided. You will never need to cook another meal, plan another day, or clean another mess. Sounds like an idyllic place, but no one rushes into a retirement home!
Embrace life because today your every deed is so meaningful!
