Space Exploration
"I believe every human has a finite number of heartbeats. I don't intend to waste any of mine." - Neil Armstrong
Space was, at one point, impossible to reach. People laughed at the concept and even disregarded the notion that humans would ever see it.
The impossible is never truly impossible, it's simply out of reach. If you can find a way to push past those who say you're incapable of doing something, you can expand the bounds of what's considered possible.
Most people don't want to to move out of their comfort zone and they don't want you to go there either. They can only see so far in front of them. The future seems too far away to worry about, right now is more important.
Don't let anyone pull you down. Listen, understand, be willing to shift, but never give in to the lie that you're incapable of achieving something nobody has done before.
