An Astronaut's Guide to Life on Earth

It takes years of serious, sustained effort to become an astronaut, because you need to build a new knowledge base, develop your physical capabilities and dramatically expand your technical skill set. But the most important thing you need to change - is your mind. You need to learn to think like an astronaut.

• Success is feeling good about the work you do throughout the long, unheralded journey that may or may not wind up at the launch pad.
• You shouldn't determine whether you arrive at the desired professional destinations. Too many variables are out of your control.
• There is just one thing in our control: your attitude during the journey. This is what should keep you feeling steady and stable and heading in the right direction. Losing attitude is worse than not achieving your goal.

Fear comes from not knowing what to expect and not feeling like you have control with what's about to happen. You may feel helpless, more afraid than you would be if you knew the facts. if you're not sure what to be alarmed about, everything is alarming.

Life is just a lot better if you feel you’re having 10 wins a day rather than a win every 10 years or so.

If you're striving for excellence whether playing guitar or flying a jet - there is no such thing as over-preparation. It's your best chance of improving your odds.

This skill isn’t just useful for going to space though. It helps to be ready for any obstacle that suddenly shows up. When I lost my job last year, for example, some of my preparations made that a lot easier. 

• Living in space requires a lot of preparation, which is a key component to having a good life on Earth no matter what you do.
• If you want to survive as a space explorer, you’ve got to learn how to take criticism, which is a skill we can all learn to be happier.
• Coming back to Earth after being in outer space is difficult, but also gives astronauts a new outlook and sense of appreciation.

If you want to become truly exceptional, you’ve got to try so you learn how not to do whatever you’re working toward. That means you have to welcome any feedback, including negative, if you want to improve.

Taking correction well is especially vital if you’re on a team like astronauts are. When serious problems arise the group only has each other to rely on. And if you can’t roll with the punches of criticism from your teammates, it will be hard to work together in life or death scenarios.

If you think the trip to space is hard, wait until you hear about the way back. The Russian Soyuz spacecraft is the only way to and from the International Space Station. And the hour-long landings are notably turbulent. 

It’s also hard to adjust to normal life after getting home from a space mission. In zero gravity, your body’s muscles deteriorate. But when you return, the weight of being on earth is difficult to manage. 

Even sitting down isn’t comfortable because your body isn’t used to carrying its own weight.
