Before He Passed, This Man Wrote And Recorded A Beautiful Letter To His Daughter. Here's What It Said.

"Enjoy your life. Don’t rush through it. I will be waiting."

Last week, a brain tumor took Tom Attwater's life. But he didn't go without leaving behind some beautiful words for his 6-year-old stepdaughter, Kelli.

Prior to his passing, Attwater and his wife started the Kelli Smith Appeal with the hopes of raising money for Kelli, who was diagnosed with neuroblastoma, an aggressive type of childhood cancer.

"There is no treatment protocol in the UK for relapsed Neuroblastoma, however there are options available abroad. Sadly these treatments could cost in excess of £500,000. We know this is a huge price tag, but we have seen other children in Kelli's situation reach their target and go on to receive the life saving treatment they needed, and it has worked! Kelli is still smiling," the family wrote on their website.

According to The Mirror, the loving father raised the money before passing on September 29.

"Tom swore he could not die in peace unless he knew he had done everything he could to ensure Kelli lived a long life," The Mirror writes.

But even more beautiful than the money, Attwater left behind a published, heartfelt letter, complete with a video of him reading it directly to Kelli.

Highlighted below are some of the most touching points from the letter reading:

"While your old dad is still around I thought I'd try to give you some life advice in one go. I hope it gives you some comfort."

"You might remember seeing your mum and I laughing together and cuddling on the sofa, and once the love hearts and flowers fade that’s what real love looks like. Have fun finding it, darling."

"I always dreamt about your wedding day and imagined filling it with tears as I walked you down the aisle before giving you away. I won't be able to do that Kelli. Sorry sweetheart. But I will be looking over your shoulder on that day, proud and happy you have found a special someone to love you and care for you."

"Nothing is more important than family and the values they give us. Nothing."

"Do what makes you happy and that you enjoy. If you do that, life suddenly becomes much, much easier."

"Always keep trying. You might remember that I taught you to say "giving up is for losers". I failed a number of times in my life but never gave up. Kelli, never give up. Enjoy your life. Don't rush through it. I will be waiting."

What important, beautiful words to leave behind.
