How many times in life have you thought about quitting your job to do something you love instead?
Huda Kattan made that decision 10 years ago and now runs beauty empire Huda Beauty, which Forbes recently valued at over $1bn (£800m), the BBC reported.
The American left Dubai - where she had made her home for two years - and her job in finance and headed to Los Angeles to become a make-up artist and start her own beauty blog.
It was only when she started making her own false eyelashes - because she couldn't find any she deemed suitable for her clients - that she realized there was a huge gap in the market, the BCC said.
"I didn't necessarily know if I belonged in the beauty industry, I always knew I had a love for it, but my family wasn't necessarily into something like beauty or fashion," Huda, whose parents were Iraqi immigrants, tells the BBC.
"They were very much into having serious jobs like a lawyer or a doctor, those were the kind of things my family wanted me to do, so it was kind of a big deal for my family.
"I felt like they were disappointed at first, so I knew that I had to prove something to be taken seriously."
When the 35-year-old started her false eyelash business in 2013, she already had a good base of potential customers - the people who read her blog and followed her on social media.
But she might never have got the business off the ground if it wasn't for her sister, Mona, who is now Huda Beauty's global president.
