Step 1: Wake up. Realize the world is doomed. Cry for 10 minutes.
Step 2: Develop an elaborate plan involving cats, robots, and a time machine. Ignore the physics.
Step 3: Convince others to join you. This may involve bribing them with free food.
Step 4: Implement steps 1-3 while ignoring steps 2 and 5. Repeat as necessary.
Step 5: Realize too late that the world was never really in danger and you've just wasted a lot of time and money.
