The Bolton hero, still reeling from his shock 30-second destruction by Breidis Prescott, believes he has made the right move.
Khan makes his comeback at London's Excel Arena on December 6 as chief support to Dagenham fighter Nicky Cook, who will be making the first defence of his WBO super-featherweight title.
The lightweight has now linked up with top trainer Freddie Roach at his Wild Card gym in California to focus on his boxing and get away from the trappings of stardom at home.
Some in the Khan camp felt the 21-year-old was spending too much time on celebrity appearances and charity and community events in the run-up to his quickfire KO by Prescott.
Khan sacked Cuban trainer Jorge Rubio following that one fight and after searching the US for a replacement, plumped for Roach, whose charges have included Mike Tyson, Oscar de la Hoya and Bernard Hopkins as well as current world pound-for-pound number one Manny Pacquiao.
And Khan is enjoying the freedom and relative obscurity of life away from the British media spotlight and in a learning environment.
"It's been great out here, I'm not distracted with anything outside of boxing and all I do is train and learn," he said.
"I'm working on so much stuff with Freddie that I'm going home more mentally tired than physically tired!"
Khan believes he will learn from the Prescott defeat, and that we will see a more measured boxer in future.
"Although the loss to Prescott was a big blow, it was perhaps the best thing that could have happened to me because it made me realise I had to change things and I've made the right move to Freddie," he said.
"I'm really looking forward to my comeback fight and showing everyone that I am back and have even more determination to reach the top."
Promoter Frank Warren, who approved of the link-up with Roach, said: "All eyes will be on Amir in his first fight back and he needs to prove that he is a better fighter, which I'm sure he will do." Tweet

Steps out of the spotlight??? Correction, knocked out of the spotlight!
amir said his new sparring partner in photo is a lot better....as it does not hit him back......and that is lot better for him....and that doing 12 rounds with it would not be a problem....
Amir who?
Wasn't he the kid that got beat in the Olympics final?
Horrible personality, big mouth, criminal with no morals, GLASS JAW.
That just about sums up Amir Khans career.
Retire Amir, that will cheer everybody up no end, no one likes you, thats why the cheers were louder than the groans when you got sparked out at the MEN.
You can't put muscles on a chin!
amir did not bounce up like thought !!it was more like a 56ib bag if spuds hitting the floor....i did like the foolish attempt to carry on..as it must have resulted in more stars before his eyes,his legs went like a rowntree,s jelly....
