Highest of heavens

[50cent]

Salaam I've experienced a situation in life which broke me completely and I didn't have hope or want to live anymore. Allah gave me something that I loved and then took it away and I wasn't myself for many many years. Until I found out about the decree of Allah and know Allah always does things for the best and the only thing that is better than what he gave me is to go heaven which is the only thing I want now and don't care about this world, alhumdulilah, I learnt I experienced this and it broke me because Allah wants my heart to not ever be attached to this world, be close to him and go to the highest of heavens.


So my question is, what can I do to make sure I go to the Highest of heavens.
Apart from praying and doing the 5 pillars, what else can I do? What duties and very very rewarding?
