Seems so simple

بِسْمِ ٱللَّهِ ٱلرَّحْمَٰنِ ٱلرَّحِيمِ قَدْ أَفْلَحَ ٱلْمُؤْمِنُونَ

Successful indeed are the believers.

The first 11 ayats of surah muminoon detail how to obtain the highest Heights of Paradise and it is not incredibly overwhelming. Just a few basic things that anyone can do. Don't listen to trash talk (television, movies, some music) pray all of your prayers and on time. Honor that which has been entrusted to you. Basically do your job as a Muslim and you can get in.

Of course everyone will tell you that toy have to do extra, but those are only insurance policies in case you don't get the basics right. It's so simple. So why do we have so much problems?

Read those ayats and see what I'm talking about.
