For Sinha, cricketer Yuvraj Singh has been an inspiration. "He sent me a cheque of Rs.1 lakh and also spoke to me when I was recovering. I then got to know later he was diagnosed with cancer. When I saw him back in the Indian team I was inspired and said to myself that if he can get back to the team, I could do something with my life."
In September 2012, Sinha had climbed 21,110 ft of Mt Chhamser Kangri's (21,798 ft). She had to abandon the expedition 690 ft short of the summit due to bad weather condition.
Arunima successfully scaled the 6,622-metre-high Mount Chhamser Kangri of Ladakh last year, but her ultimate goal was to climb Mount Everest.
Yesterday, two 21-year-old Indian sisters scripted history by becoming the first twins ever to conquer the summit of Mount Everest together.
Tashi and Nancy Malik from Dehra Dun achieved this feat along with other record-makers, including the first women from Saudi Arabia and Pakistan to have climbed the peak.
