"Dude, can you just not be evil for like 50 years?"

Because life is not too long, we should be able to keep on track the whole while -- it's not outside our power.

"stay the course" is mostly nautical, means keep going straight, i.e. staying on the wanted direction despite small variations of wind or waves.

Oh wow, this worked for me too. Scroll up a page, then scroll down. You can keep reading.

(Thanks, also works for me.)
