Justin Bieber
Bieber's tattoos largely don't have much meaning besides their aesthetic purposes and references to faith. This tattoo has a direct meaning as to how Bieber wants to live his life. The way he sees it, he wants everything in his life to be "better at 70." This tattoo is supposed to inspire Bieber to keep pushing on and succeeding in life, so by the time he's 70, he can look back and know that he lived a good life.
