Whether it's The BFG, Fantastic Mr Fox, Charlie and the Chocolate Factory, Matilda, or one of the many other brilliant books he wrote, we've all got a Roald Dahl story we hold close to our heart.
Filled with tales of adventure, bravery, magic and fun, these spellbinding stories are not only alive with imagination, but also contain some important life lessons we can all learn from.
In honour of Roald Dahl day - his birthday; 13 September - we've picked out four of our favourite Roald Dahl quotes that are relevant and poignant, whatever your age.
1 "A little nonsense now and then, is relished by the wisest men"
Charlie and the Great Glass Elevator
Roald Dahl's books share stories of bravery, adventure, self belief and - most of all - fun. In Charlie And The Great Glass Elevator, Willy Wonka reminds the grown ups of a very important thing - not to take life too seriously. And in our busy, modern lives, this feels more apt than ever.
2 "Those who don't believe in magic will never find it"
The last line in Roald Dahl's The Minpins is hard to forget, "And above all, watch with glittering eyes the whole world around you because the greatest secrets are always hidden in the most unlikely places. Those who don't believe in magic will never find it."
Look for the glimmers of good. Keep an open mind. Look up from your phone. Don't get too caught up in yourself.
He really is a genius - however you want to interpret it.
3 "The matter with human beans is that they is absolutely refusing to believe in anything unless they is actually seeing it right in front of their own schnozzles."
In The BFG, humans don't believe in giants because they keep themselves out of sight - but that doesn't mean they're not there!
He cleverly reduces adult behaviour to banal silliness in his tales. We should take note!
4 "Somewhere inside all of us is the power to change the world"
When Miss Trunchbull tells Matilda "I'm right and you're wrong, I'm big and you're little and there's nothing you can do about it," Matilda proves her wrong in the end.
From Charlie and the Chocolate Factory to The Witches, many of Roald Dahl's stories are about the underdog coming out on top and setting the world to rights - it's just about getting on and doing it. So believe in yourself and go forth and conquer!
