That is true for writing poetry, i believe. writing for earning money leads to creating contents like, fire birgade mangwa day tu angaroon par hain armaan.
Or noshi gilani was wrong where she said,
Kisi maa ki dua ki tarah hoti hai.
shaayri radd e bala hoti hai
Mohsin Naqvi.
Tumhari soch bhi aakhir behak gaee Mohsin
Tumhain to shehr main roshan dimagh hona tha.
