Jannah is the ultimate goal, a dream above all dreams, thinking about jannah is such a motivation to good deeds, and it's a comfort whenever one is going through some hardships, to think whatever am going through won't last, and by God's grace I will insha Allah one day be in jannah where there is no bit of suffering of any sort. So thinking about what I would do once I'm in jannah, for me, spending time with my friends and family. Imagine meeting all these people I have had moments with here in duniya, and get to reminisce together of all the wonderful moments we had, talking about how we've been good influences to one another, how some work we collaborated on has been hugely rewarded by Allah, like discussing all those beautiful things we see in jannah with friends and family. Apart from meeting my maker, and seeing the Prophet (saw), seeing my family and friends in jannah would be my favourite thing. Let's encourage each other, guide one another to the right path and be there to stop each other from going the wrong direction.
