The Success Kid meme features a photo of 11-month-old Sammy Griner clutching a handful of sand at the beach in 2007. Originally posted to Flickr by his mother, Laney Griner, the image was first titled 'I Hate Sandcastles.' However, the internet soon transformed the toddler's determined expression into a symbol of triumph and unexpected good luck. Since then, it has become one of the most wholesome and enduring memes, even helping to raise money for Sammy's father's kidney transplant in 2015.
