we must be smart enough to know we lost the battle but we will win the war
I'm not sure that I'm "smart enough" or if in fact "smart" has much to do with it at all.
I've lost my fair share of battles but always win the war, because I always maintain at least one and often multiple disk images and with an SSD imaging to USB 3.0 external storage it's about a 14 minute round trip ( 7 minutes to create the image and about the same to restore it) to recovering my system to a relatively recent point in time.
Consequently I enjoy a fair bit of fearlessness with respect to Windows Updates or other potentially more catastrophic problems with hardware failures or OS file system corruption, especially on my second machine where I am testing the latest preview builds.
I've found that I can't always rely on the native troubleshooting tools within Windows 10
System Restore, Startup Repair, Go Back To.... or even Reset
To rescue me from either Microsoft or myself, so I've chosen third party software (Acronis True Image) to bail me out of the hot water I occasionally find myself in.
