Looking after Lewis Hamilton sounds like a job for an au pair.
On the surface he appears high maintenance, immature, prone to whinging ... but the Kiwi who runs his life at grand prix weekends says there's another side of Hamilton the public doesn't see.
On paper, Angela Cullen is described as the three-time Formula 1 world champion's physiotherapist. In reality she's a high-powered personal assistant.
Cullen would know - her job description sees her responsible for almost everything Hamilton does as he heads off around the globe to a race weekend.
"I'm called a physiotherapist but the role is a performance coach role," she says.
"My role is to basically, over the course of the race weekend, eliminate any external factors so he only has to think just about his driving and not have to worry about any other things.
"I wake him up in the morning, I order his food, I drive him to the track, I manage his whole schedule for the weekend and basically eliminate anything over the course of his weekend that could take energy away from him thinking about his race day and making sure his performance is 100 per cent."
That time alongside the precocious Brit has given her a first-hand understanding of the way he really ticks away from the public gaze and the glare of the television cameras.
"He is incredibly humble and incredibly respectful and I think the media give him such a hard time," Cullen says. "I think it's just one of those scenarios where, when you are at the top of the game, you are going to be the person that gets taken down.
"It frustrates me so much because the side I see doesn't come out in the media.
"There is not a day or a race where I leave and I don't get a look in the eyes or a text thanking me for what I do. He is very thankful of those that work hard around him.
"I'm not someone who would just do the job because the job is kind of exciting - I need to be working for someone I really want to help and he really does instill that in me.

"He is the most amazingly talented and dedicated athlete but not just in sports. He has some big goals outside of sport. He is producing his first music album. He has been working hard on that."
Based in Geneva, Switzerland, working for Hintsa Performance, Cullen has a long history in sport.
"I have been working in high performance sport for 25 years - I started working with the British athletic team working with 100m and 200m sprinters 15 years ago and that was very much a physiotherapy role but, over the course of working with elite athletes, you start developing more of a mentor role and facilitating more of a performance role.
"I found as a physiotherapist, you spend a lot of time talking to your athletes and learning and understanding them and helping them work through other problems in their lives as well. I naturally developed in to a performance coach role."
Hintsa Performance has a long history in Formula 1 and is about matching performance coaches with drivers and looking at all areas of health and well-being.
"I came on as the biomechanics expert and I worked with 12 drivers across the grid," Cullen explains.
"They had contracts with our organisation and we provide a performance coach as well as support across all areas.
"I met Lewis, I met Nico [Rosberg] and Daniel Ricciardo - they all came and saw me. Over the course of the year they would see me two or three times and I would work with their coaches to make sure they were following a good biomechanics injury prevention programme. I worked with Lewis over the course of 2015.
"You get to chat and we connected really well and, at the end of last season, he asked me to come and do all the races with him. I thought he was joking to be honest because they don't have any female coaches in Formula 1.
"This is my first season working with him - 21 races and I have spent 180 nights away - it was obviously a crazy season to get involved with him. He is someone who is very driven and focused on winning a world championship and that has been quite challenging for him mentally."
The major talking point all season was the inter-team battle between Hamilton and Rosberg - with the latter breaking through for a maiden title before promptly announcing his retirement from the sport.
The media interest around the battle between the Mercedes teammates and childhood friends bubbled along all year and saw their relationship called in to question on a number of occasions.
Cullen saw it up close and admits it was a topic she worked on with Hamilton.
"They have been racing together for 18 years - they were best friends. They used to travel to race meetings together when they were younger. [The rivalry] is certainly there - it is real.
"I think when you have got two top drivers battling for a championship, you couldn't expect anything less than a bit of rivalry. There is a lot of respect for each other as drivers but there is a lot of tension in the garage because they both want to win.
"I don't think you could ever be best friends while you are competing like that but I think it will progress back to being friends now that Nico has retired."
Hamilton's lifestyle and personal life have long been a source of interest in the tabloids.
He dated popstar Nicole Scherzinger on and off between 2007 and 2015 and was constantly portrayed as someone who liked to party.
"He occasionally does crazy things but no more than any normal person - it just gets blown out of proportion because of who he is.
"I have spent the whole year with him this year and we might have partied maybe four times - I don't know too many people that would only go out and party four times in the course of a year.
"He is not a party boy. If he has a three-week recovery between races he might have a drink to celebrate a race win, but if there is a race meeting the next week, he won't drink at all."
Cullen will continue the relationship with Hamilton into 2017 but nominates a couple of moments that stand out from her first year working alongside him.
Hamilton often rides a motorbike while at European tracks and Cullen shared a high speed ride with him on arrival at Spa in Belgium. "I closed my eyes and thought to myself that this guy knows what he is doing but I was packing myself," she says.
Having arguably the best driver on the planet as a back-seat driver while she ferries him to a race track in a foreign city also stands out.
