I always had this instinct that i don't want to be an earning animal. I get calls for jobs but i dont go for interviews as I feel it is not going to benefit me in the hereafter. Please advise what should I do?

This kind of thinking is unnatural, and also un-Islamic. It is everyone's natural need to earn so that he can fulfil his basic necessities. It is the lawful requirement of every human being. Even the Prophets earned to fulfil their need. For reference, please see Hadith No. 2073 in Sahih al-Bukhari
For the purpose of life, please read my books. Four of these are raaz-e-hayat, tameer-e-hayat, rahnuma-e-hayat and kitab-e-zindagi. All these are available on the cps website www.cpsglobal.org
