During an interview, while talking about his motivational videos, he said, My first ever video was about demotivating people. But I dont call myself a motivational speaker; I talk about what I have experienced in my 29-year-old life very simple and relatable things, as you can see. Things we fail to notice. When the number of followers increased, people started to direct message me. I get a minimum of 2,000 messages every day, from eighth graders to middle aged men. I found that they feel comfortable to disclose their problems to me. I never knew I could make such a difference. I reply to every text message, hoping that my little effort may help them. On the other hand, I am a very normal person. I can be upset and moody at times. But when its about bringing smile on someones face, I try my best to be selfless..Dr Robin has also featured in Malayalam cover songs such as Mizhiyariyathe (2018) by K S Harisankar, Pavizha Mazhaye (2019) by K S Harisankar, and Jiya Jale (2019) by K S Harisankar.He acted in the Malayalam short video Niram in 2019.
