Never be limited by other people’s limited imaginations. There were people who said, “You can’t go into space. You can’t go to the moon.” If you adopt their attitudes, then the possibility won’t exist because you’ll have already shut it out. Yes, you can hear other people’s wisdom, but you’ve got to re-evaluate the world for yourself.

Mae Jemison (b. 1956) American engineer, physician, astronaut
