@infinite.motivation4: There was a time when computers were becoming powerful enough to perform calculations that once required humans. But before John Glenn trusted the computer's numbers, he wanted Katherine Johnson to check them herself. She didn't become important because someone handed her an easy opportunity. She became valuable because she had spent years becoming exceptionally good at what she did. Sometimes your breakthrough doesn't begin when people notice you. It begins years earlier, when you're working quietly and becoming impossible to ignore. #motivation #believeinyourself #mentalstrength #stayhard #discipline #mathewmcconaughey #mathew
