After this he started making motivational videos on Instagram. Talking about making motivational videos in an interview, he said,

My first video was about ‘demotivating people’. But I don’t call myself a motivational speaker; I talk about what I have experienced in my 29 years of life – very simple and relatable things, as you can see. Things we fail to notice. When the number of followers increased, people started direct messaging me. From eighth grade kids to middle-aged men, I get at least 2,000 messages every day. I found that they feel comfortable telling me about their problems. I never knew I could make such a difference. I answer every text message, hope my little effort can help them. On the other hand, I am a very normal person. I can be upset and moody at times. But when it comes to putting a smile on someone’s face, I try my best to be selfless.”
