Need is challenge

Subjectively we dont have need to discuss anything but necessarily we discuss the things and fact because we try to understand and accommodate ourselves. However,  need is more practical and genuine thing which attract disturb and encourage to human as well as animal to do in respect to fulfil it. Our behaviour our attitude our nature and specially our thought depends upon our need and its fulfilment. Need is a challenge to maintain our stability  in all spheres of life mentally emotionally. 

Thanks.
