There are four things that are signs of a condemned person.
The first one is to stay jahil [ignorant] of important knowledge.
Some people may perform salah for 60 years without one of their salah being accepted. This is because they haven't learnt how to perform.
Some people don't sit in between the sajdahs.
We can't do any other action before the imam.
If you want to know whether your salah is correct or not, ask someone who has ilm.
To not learn how to perform salah, is ignorance.
Not knowing how to recite Quran is also a common ignorance. We should go to learn. Some people know how to do everything in life except how to recite Quran.
The second sign is laziness. People are lazy to perform salah. It is a great sin. The cure for laziness is activeness. If you feel lazy to wake up for fajr, rub your eyes, use your miswaak and get out of bed straight away. Or splash your face with water.
If you can't wake up for fajr, recite the last three ayahs of surah kahf before going to sleep.
The one who is lazy will be unsuccessful.
There was once a boy who would sell ice daily. One day noone would buy his ice so he started crying. A man came to him and asked his reason for crying. He said that noone was buying his ice and it was melting, if he went home without money his mother would be upset. So this man bought all the remaining ice.
Maulana Rumi RA likens this to life. Our life is melting away just like this ice was melting away. We don't have long left to live. Noone lives forever.

O Allah give us the tawfiq to perform our prayers correctly.
O Allah give us the tawfiq to recite the Quran Kareem with the correct Tajweed.
رَبِّ اجْعَلْنِي مُقِيمَ الصَّلَاةِ وَمِن ذُرِّيَّتِي ۚ رَبَّنَا وَتَقَبَّلْ دُعَاءِ
My Lord, make me an establisher of prayer, and [many] from my descendants. Our Lord, and accept my supplication
