If you can't stand the heat, then stay out of the kitchen.
If the task you are pursuing puts too much pressure on you, then you should not pursue the task. (Especially if the pressure exceeds the benefits of the task.)
My boss saw that I was in panic mode to get my job done today. Instead of words of encouragement, she said to me "If you can't stand the heat, then stay out of the kitchen." ..What a bitch!
