The biggest risk is not taking any risk... In a world that changing really quickly, the only strategy that is guaranteed to fail is not taking risks.
You must accept that you might fail; then, if you do your best and still don't win, at least you can be satisfied that you've tried. If you don't accept failure as a possibility, you don't set high goals, you don't branch out, you don't try - you don't take the risk.
Normally, in the presence of radiation, communication links fail. But with autonomous robots, you don't need communications.
Take chances, make mistakes. That's how you grow. Pain nourishes your courage. You have to fail in order to practice being brave.
Your competition is not other people but the time you kill, the ill will you create, the knowledge you neglect to learn, the connections you fail to build, the health you sacrifice along the path, your inability to generate ideas, the people around you who don't support and love your efforts, and whatever god you curse for your bad luck.
What great thing would you attempt if you knew you could not fail?
Take those chances and you can achieve greatness, whereas if you go conservative, you'll never know. I truly believe what doesn't kill you makes you stronger. Even if you fail, learning and moving on is sometimes the best thing.
Ever tried. Ever failed. No matter. Try Again. Fail again. Fail better.
The greatest humiliation in life, is to work hard on something from which you expect great appreciation, and then fail to get it.
Think like a queen. A queen is not afraid to fail. Failure is another steppingstone to greatness.
