For the last two years, 17-year-old Greta Thunberg has been a seemingly tireless advocate for global action preventing the disastrous effects of climate change.
As the BBC reported, she began by taking Fridays off from school to protest in front of the Swedish parliament building two years ago, but is now a symbol of a worldwide grassroots movement taking action against the climate crisis.
Even putting aside the frequent attacks against her from those whose interests are threatened by her calls to action, her high profile entails a lot more responsibility than the average teenager is expected to take on.
But based on how she characterized a landmark meeting with another global icon for change, it's clear where she got some of her inspiration to carry on.
