Believers are on a path of continual improvement ... 
People do make mistakes ...
But believers analyze their mistakes and take positive actions to correct them ... 

This examination is critical for creating purity in every action ... 

In this way 
Believers develop a lifestyle which is firmly grounded in the principles of faith 
And as loved by Allah (SWT) and His Noble Prophet Muhammad (SAW) ...

All the sons of Adam are sinners ... 
But the best of sinners are those who repent ...

Dua: 

O Allah 
Let us become better Muslims by repenting for our sins ...
Major and minor
Intentionally or unintentionally
Openly or secretly 
And accept our repentance  
And save us from repeating our sins 

Ameen
