Teenager Stephen Sutton, who dedicated his life to spreading happiness and inspiring others, has lost his cancer fight, aged just 19.
Despite suffering from incurable metastatic bowel cancer, Stephen remained determined to experience life - writing a 46-point bucket list of adventures to complete along the way.
Here are some of the teenage inspiration's most memorable quotes:
I'm not afraid of dying, I'm afraid of not cramming as much into my life as I should have done.
"I don't see the point in measuring life in terms of time. I'd rather measure life in terms of making a difference" http://t.co/RzkfI327Vp
It is not the situation, it is how I react to the situation that is important.
Spread as much positivity as possible - that's my goal.
When you look at the positives of life, there is so much to enjoy, there is so much to be excited about.
We are on the journey together. This isn't about me, it's about helping others.
There is only so long that you can ask, 'Why me?'
I have been to a place that makes you realise life might not be fair, but that realisation pushes you to make it a better place.
I am not suffering from cancer, I am living with cancer. I am not cancer.
Make every second count, never take anything for granted, don't be afraid to try something new - life is for living.
From someone who wants more time in this world, please don't waste yours, you'd be amazed what you can achieve when you try.
