I have a few.
J.K Rowling - she got turned down over 40 times for her Harry Potter books and still persisted
Markiplier - he's just a really good-natured man and I love him to bits
Robin Williams - in spite of fighting depression and other things before he took his own life, he continued to make others smile
My mother - she had her own problems before she passed, but she was a warrior and I hope I can be the same
