The 69-year-old is enjoying his second spell with the Blues but maintains he will retire from coaching at the end of the season
The 69-year-old took charge at Stamford Bridge for the second time in his career in December after Jose Mourinho left the club following a turbulent start to the campaign.
Hiddink has helped the Premier League champions regain some solidity and only suffered his first defeat of the season when his side were beaten 2-1 by Paris Saint-Germain in the first leg of the Champions League last 16.
Though the former Netherlands boss plans on visiting the club beyond the end of 2015-16, he maintains that he will not go into another coaching role once he leaves London.
"I feel fit, I feel fresh and, every morning, I go with a smile," he said. "Although we have a difficult time when there's a loss, I love to go to Cobham, to the training field, so I feel fresh.
"On the other hand, young people must take over and I must retreat a bit. I will visit Chelsea often next season but I'm not thinking of working elsewhere."

Yet despite his comments, midfielder Oscar is quietly optimistic Hiddink may yet decide to stay on at the club next season if offered the chance, admitting he has had a "positive influence" since joining.
"Based on how well Guus has been doing so far, he could very well stay," he told The Sunday Times. "He's a very nice guy. Very smiley. He always looks to create a happy, positive environment.
"He has a very positive influence here and we've been playing well. We've had a lot of draws in that time but overall, in the Premier League, things have been going a lot better and it has given a huge boost of confidence to all the players.
"And also for me on a personal level because I'm playing much better.
"He said all the things we wanted to hear as players which was to get back to winning ways and playing much better football like we were doing so last season, so that was the main thing -- getting back to the level we know that we can perform at."
"Since he's a popular figure, there's a good chance he'll stay."
