Hi I have completed BE Electrical and working in Big 4 as a executive. But right after securing admission in BE and introduction of smartphone in my life I got addicted to social media, porn, peer pressure. Due to which my life started moving downwards. I'm not able to achieve my goals, when I prepare my plans I'm not able to adhere to it strictly. I want to crack UPSC, can you suggest me things to improvise in my life to reduce my addictions and narrow down my routine to achieve my goals.
