If you've ever dragged yourself into work with a cold and acted like it's the greatest sacrifice since Bruce Willis stayed behind to blow up that asteroid, consider this: Ella Eyre shot one of her latest videos with an agonising kidney infection.
The 25-year-old woke up one day last September with a pain so bad that she thought her appendix had burst.
"I was like, 'Am I in labour? Is there something I don't know?'" she recalls.
But instead of crawling under the duvet and bursting into tears, she stumbled into her nearest A&E, got some pain medication and boarded a flight to Ukraine.
"I'd have been in more pain at home doing nothing than being in Kiev shooting the video," she argues.
While her actions aren't medically advisable, they help explain why Ella Eyre is still making music after what can generously be described as a "choppy period" in her career.
It's been five years since her debut album, Feline, went Top 10. A follow-up was due in 2017, but never materialised.
Upheaval at her record label, Virgin EMI, meant the people who'd signed Ella as a teenager had left. Their replacements weren't sure what to do with her, a symptom of the UK music industry's mystifying inability to understand or sustain the careers of female artists beyond an initial flush of fame.
Essentially, Ella says, she'd ceased to be anyone's "passion project" and her music kept slipping off the release schedule.
"I've had that so much in my career, where I've written great songs and they want to save them, but we've never got to the point we were saving them for.
"It was just frustrating because the delay sets doubt in your mind. I think if you don't have any doubts about the music, you should release it straight away.
"Don't sit on it because then someone will turn around and say, 'Oh, that would have been good a year ago, but not so much now.'"
'New Me'
Ella eventually parted ways with Virgin but she "made sure the ball kept rolling", appearing on Celebrity Bake Off (her pineapple meringue tower was a sight to behold) and, more importantly, lending her gravelly vocals to top 10 hits like Sigala's Just Got Paid, and Banx & Ranx's Answerphone.
When the latter became a radio smash, there was suddenly "no shortage of people that wanted to be her record label," Ella's manager told Music Week last year.
They eventually signed to Island Records which, through its work with Ariana Grande, Robyn and Sigrid, has a history of championing female pop artists with a distinct point of view.
Fittingly, Ella is rebooting her career with a song - New Me - that sees her shrugging off the past and striking out on her own.
"Ella ain't here, it's a new me," declares the singer over an infectious, dancehall-inspired beat. And while the lyrics are ostensibly about a toxic relationship, they could easily refer to her professional rejuvenation.
"It's a metaphor in so many ways," she agrees. "I feel like a new artist because I'm coming at it from a very different understanding of the industry."
"When I first started, I was 16 and I was so doe-eyed. When one of the record labels says to you, 'We don't just sign everything and see what works,' you're like, 'Wow, I believe you.'
"This time round, I was like, 'Rubbish! Lies!' I just have a much better understanding of the way I want to manage my campaigns and how I want [my] music to be received and delivered.
"I feel like a boss. A boss woman."
