One can usually expect a proud new father and a world no.1 in his professional field to be full of optimism and confidence, and it's certainly the case for Novak Djokovic as his campaign to bag a third successive ATP World Tour Finals title draws closer.
As is the case in most the tournaments he takes part in at the moment, the Serb is the favourite to win. He will look to end another dominant season on a high at London's O2 Arena when the Finals kick-off next week.
The 27-year-old returned to action following the birth of his first child, a baby boy named Stefan, at the recent Paris Masters and showed no ill-effects of sleepless nights, as he cruised to the strangely-shaped silverware without dropping a single set in the French Capital.
Djokovic will be hoping to repeat the winning-trick as he heads across The Channel, past the white cliffs of Dover and into the River Thames-side Arena in London. The Finals will hold no fear factor or nasty surprises for the seven-time Grand Slam champion, he's already won it three times before; including twice in the last two years.
"It definitely encourages me the fact that I have played so well [in Paris] and that I have won the past four indoor tournaments in the past two years that I've played," Djokovic told the ATP ahead of the Finals.
"From outdoor hard court that was my most successful and most preferred surface, now I guess it's an indoor court. I do feel very comfortable playing, returning, serving in these conditions."
Indeed Djokovic can feel vindicated in his own confidence to play a good match indoors, he's currently unbeaten in 27 matches under a roof after coming out of Paris completely unscathed.
Of course, that's not to say the world no.1 will not be given a stern test in England. All seven of his other competitors have had to perform consistently well to book their spot.
Djokovic, winner of Wimbledon this summer, faces both the Australian Open and US Open winners, Stanislas Wawrinka and Marin Cilic respectively, in the first group phase. World no.5 Tomas Berdych completes 'Group A'.
Potentially meeting Djokovic in the later rounds is his rival for the world's year-end top spot, Roger Federer, and the likes of Andy Murray, his beaten Paris finalist - Milos Raonic, and Kei Nishikori.
Even without the injured Rafael Nadal - the field is strong, nonetheless Djokovic is confident of performing well again on the big stage.
"Two successive titles in London in the past two years give me reason to believe that I can do well," he continued.
"I have a week off to recharge my batteries, recover a little bit, spend some time with family, and get on the court.
"I'm excited to be there, because I think it's one of the most spectacular tennis venues that we have. People in London love tennis and have appreciation for this sport. So I look forward to that."
No man since Ivan Lendl in the 1980s has won three consecutive Finals titles, and Djokovic will begin his bid to repeat Andy Murray's former coach's heroics with an opener against Cilic on Monday. The Croatian, a shock winner at Flushing Meadows this year, has never beaten the top seed.
