At an Age of 16, when no usual kid from Noida could dream of standing on top of Mt. Everest, Arjun had already done that. The journey started with a small dream which he saw at the age of 14. Arjun was an excellent athlete during his school time at Ryan International School, Noida and after his class 10th boards, he was enrolled into Basic Mountaineering Course. Arjun's Father, being an Ex-Army Officer himself, encouraged Arjun to be involved in things where he had an opportunity to learn and grow. After his Basic Mountaineering Course at Nehru Institute of Mountaineering, Uttarkashi, Arjun returned to the same Institute for his Advanced Course in 2009. During his Advanced Mountaineering Course, Arjun became the Youngest Person to reach Mt. DKD II summit. He returned safely to his home after Advance Course and started preparing for the Journey which later became History.
With the help of his Parents, Relatives, Friends, School and Contribution from more than 25,000 people from across the nation who came to know about Arjun's dream to become Youngest Person in the World to summit Mt. Everest through various media platforms, Arjun was ready to achieve the Impossible and started his journey to World's highest Mountain at an age of 16.

Arjun reached the Summit of Mt. Everest on 22nd May 2010. Arjun became The Youngest Person in The World to Summit Mt. Everest in 2010 at the age of 16.
After his successful expedition to Mt. Everest in 2010, Arjun set his eyes on his next Challenge. While on his journey to Mt. Everest, Arjun also gained knowledge about the mountain next to Mt. Everest and World's 4th Highest Peak Mt. Lhotse. Standing 8516m high, this Mountain shares the same BaseCamp as Mt. Everest. Arjun left for his next 8000m expedition in less than 365 days, and on 21st May, 2011, he became The Youngest Person in the World to reach the summit of Mt. Lhotse. After this achievement, Arjun aslo became the Youngest Person to reach the summit of 2 8000m and above mountains under 365 days.
From one chhallenge to next, Arjun was becoming unstoppable. In 2011, Arjun left for his next expedition, this time in September, to attempt Mt. Manaslu. With his experience at Mt. Everest and Mt. Lhotse, Arjun was fully prepared to summit his third 8000m peak. on 5th October, 2011, Arjun became the Youngest Person in the World to reach the summit of Mt. Manaslu. He also became the Youngest Person in the World to reach the summit of Three 8000m and above Mountains just at the age of 17.
Mt. Makalu is till date Arjun's most difficult mountain. This mountain taught Arjun a lot and he often says in interviews that whatever he is today, is because of what this miuntain has taught him. it took Arjun 4 attempts to reach the summit of Mt. Makalu. Makalu is the fifth highest mountain in the world at 8,485 metres (27,838 ft). Arjun gave his first attempt in 2013 where he was returning from a heroic comeback after Mt. Cho Oyu lefy him paralysed and "almost dead" in 2012. He was unable to reach the summit in 2013, so he returned in 2014 to finish what was left undone last year. This year too, Arjun had to return, unfortunately 120m short from the summit because he and the team attempting the summit push with him ran out of ropes. One wrong decision at that time determines life and death. Arjun came back and left no stone unturned for his preperation in 2015. This was the year when nature decided to stop Arjun's march towards the summit. A deadly earthquake hit the area and Arjun had to return after a heroic rescue. After three attempts, Arjun came back in 2016 and did what seemed almost impossible until it was done. He became the youngest person in the World to reach the summit of Mt. Makalu and ending a long journey. Arjun terms this journey as "University of Makalu".
Arjun's first encounter with Mt. Cho Oyu was in 2012. Arjun, by now had already been successful in his expedition to Mt. Everest in 2010, Mt Lhotse and Mt. Manaslu in 2011. He decided that his next challenge is going to be Mt. Cho Oyu and started his preperations. During this expedition, a disaster struck Arjun and he was left paralysed during the expedition. He was decared "Clinically Dead" and was being taken down to basecamp where he came back to life. It was no less than a miracle that Arjun survived in such horrific conditions. He returned to Mt. Cho Oyu in 2016, after his success of Mt. Makalu. On October 4th, 2016, Arjun successfully reached the summit of Mt. Cho Oyu, amking him the Youngest person in the World to summit FIVE of the total 14 8000m and above mountains of the World.
After Mt. Everest, Mt. Lhotse, Mt. Manaslu, Mt. Makalu and Mt. Cho Oyu, Arjun shifted his focus to India's Highest and World's Third Highest Mountain, Mt. Kangchenjunga in 2017. Mt Kangchenjunga is known for it's bad weather and has seen very few succesful summits in the history of mankind. Arjun had to return in 2017 due to bad weather but in 2018, he gave his all to reach the summit of his 6th 8000m and above Mountain. on 20th May, 2018, he reached the summit of Mt. Kangchenjunga, making Arjun the Youngest person in the World to reach the summit of SIX 8000m and above Mountains.
