If it doesn't kill you it only makes you stronger.
This one is a complete crock of macho motivational bullshit, mentally and physically. I've suffered a few hard physical knocks in this life and let me say: Spinal damage and dislocated limbs that leave the sufferer unable to roll from one side of a bed to another fail to engender a newfound sensation of strength and agility.
Yes, I agree. It does contain an element of truth, though. A more accurate saying might be:
What doesn't kill you:
- Might make you stronger.
- Might make you physically broken and useless.
- Might break you mentally.
- Might actually kill you.
Or it might just be reworded as,
"We often become stronger through hardship."
Another saying I find to be extremely destructive is:
"Always do your best."
This is probably the most damaging thing one can tell to a child. The implication is that you are dogshit if you are not always doing your best. And what is worse is that kids often interpret that as you are dogshit if you are not the overall best. This one stupid phrase leads to so much pathological perfectionism in the world.
I used to counter it in my kids with the following example. I say that the level of quality that is needed in a particular endeavor is a function of the endeavor itself. For example, I take the garbage cans out to the street every Thursday night. When I do that, I don't try to do my best. On the other hand, if I were performing brain surgery, I would surely be trying to do my best. Most things in life lie somewhere between taking the garbage out and brain surgery. The trick is to be able to figure out where things lie on that spectrum and adjust one's effort accordingly.
This is especially important when kids hit college and they are not in control of their workload. Professors from each course are assigning work and test dates in complete disregard for what other professors are doing. Instead of doing your best, it is a much better survival skill to become good at triage. That is more like real life anyway, since everything you put your time into has opportunity cost somewhere else.
