But as the old adage goes, one can take a sportsperson out of sport, not the sport out of that sportsperson.
Jitender Kumar was all of 20 when he lit up no smaller than the Olympic stage with a couple of lion-hearted performances before nine stitches on his jaw left him severely hampered for what could have been a historic medal-confirming bout.
That itself should have been the start of a blazing career given how boxing took off from that point in India but for Jitender, a bronze-winner from 2006 Commonwealth Games, that was the beginning of a series of lows forced by a combination of circumstances.
He is set to sign up with Infinity Optimal Solutions (IOS), the promoters who manage reigning WBO Asia Pacific champion Vijender Singh.

"It is a rebirth for me, a rebirth inside the boxing ring, is there a better way to put it? I don't know. I am coming back because of lots of pushing by my mentor Akhil Kumar and some nudging by Vijender himself," the 28-year-old from that famous cradle of Indian boxing, Bhiwani, told PTI in an interview.
But then boxing never quite left him either.
"After Beijing, I competed in the Asian Championships, (2209) got a bronze, then I competed in the World Series of Boxing (the semi-professional league run by AIBA) but after 2011, I could not continue," Jitender recalled.
Again it was a deep gash, only that this time it was above his eye, cutting short his WSB stint in 2011.
"I kept picking injuries at the wrong time. What could I do? Plus, I had to change my weight category from flyweight to bantamweight which brought me in direct competition with my mentor Akhil," Jitender said referring to the senior boxer, who shaped his career and is also taking the professional plunge now.
"Even Vijender would tell me, 'let's train together, it's always easier to train with someone along'. He would tell me how hard it is. I would say 'you are saying it's tough and asking me to come back'. Basically I had lost faith in myself," he quipped.
"I finally understood that boxing remains an integral part of who I am. I am hopeful that Haryana Police will give me permission and I would be back in the ring," said the effervescent boxer known to be a prankster among his peers.
"A police job disciplines you, one has to follow protocols. Boxing allows a little more of personal freedom. I love both though," he signed off.
