If you want to have a successful career, it can be tempting to try to be all things to all people. But, instead, you should know where to draw the line and be unashamed about saying no.
That's according to Karoli Hindriks, who, with a resume of accolades including serial entrepreneur, European Parliament speaker and MTV's youngest-ever CEO, is a success story by any standards.
However, it's a lesson she learned the hard way: When Hindriks founded her first business at 16 — a line of reflective accessories for pedestrians — she became Estonia's youngest-ever inventor and found herself suddenly in high demand.
"With my first business, I became so famous so fast," said Hindriks, whose young success saw her invited to speak at countless schools and entrepreneur forums.
"I ended up spending more time talking about my business than running it," Hindriks told CNBC Make It at "Women's Forum Singapore."
