One small screw-up and it can be all over.

I know it first hand. I got completely burnt out, ended up drinking too much, and lost everything.

At least with this career there is a chance to start over, depending on age and compensation.

But one small slip-up, whether it be a serious medical problem (especially in the US) or otherwise, and the "numbers" can be thrown out the window.

Fingers crossed.
