Hey, Preparing for CA certainly is not a cake walk. It expects high level of motivation as well as perseverance to make yourself focus and engage for long, with studies.Porn is something which would stimulate you and keep enhancing your sex drive so that you are in a state of reduced emotional engagement with studies. You need to follow few steps to engage in studies this month. 1. Find a study partner. It could be someone preparing for CA or some competitive exam seriously. If you cannot, sit in a public library away from your house and spend time there whole day. 2. Let yourself masturbate but refrain from watching porn for a month (You need to manage this habit more effectively after exams) 3. Engage yourself in jogging, exercises or Jim ming twice a day, after each session of studying. 4. Make a list of your reasons to be pursuing CA and read it to yourself first thing in the day and keep adding points. 5. Keep a certain target for the day and do not let yourself rest before reaching the target. 6. Let yourself relax and be entertained for a while every day preferably after 2 sessions. Hope you have a great time writing your exams.
