However, as we all know, Allah s' greatness cannot be comprehended by humans (or by any of His creation). So keeping that in mind, I think you should forget about the fact that Allah swt will give you "more" love if you ask Him to give you "more" than the next person, or that He will give someone else "less" because He is giving you "more". In other words, I think you're unintentionally placing limitations on Allah's mercy & treasures, even though you know that they are limitless. Allah can give the entire mankind "more" and it wouldn't have any effect on His treasures. Similarly, He can give the entire mankind "less" and again it would have no effect on His treasures. Allah's treasures are infinite and boundless.
I highly doubt that on The Last Day it will be said "well you made more dua for yourself and said to give you more attention than everyone else, so good for you here's a spot for you in Janat al-Firdous while everyone else you made (less) dua for is going to be under you in Jannah as per your wishes. Good thing you didn't ask the best for them or they might've gotten your spot". I hope that makes sense & Allah knows best.
So I guess the point I'm trying to make is that we're better off trying to make dua for everyone else and maybe even make ourselves the last ones we make dua for, and Insha'Allah if we do it with ikhlaas, The Creator will award us accordingly.
Always remember that the Prophet had fikr and made dua for everyone and he put others before himself, every single time, time and time again. If that hadn't been the case, I don't think any of us would be here on SF as Muslims discussing these things. Allah knows best. May Allah forgive me if I said anything wrong and Allah knows best.
