Why do we feel burdened to do the encouraged, and continue to do the discouraged?

It is the easy way out, a way of our Nafs & desires & we know that for sure but we give lenience to our souls.Quran & Sunnah should be the way of life for any Momin. May Allah make us the followers of it . For this we need a strong Eman which will allow us to do Mujahadah with our selves inshallah.
