How much does one moment impact a life. For example, i've read studies that a serial killer pinpointed one moment when he was young and his parents left him alone for a few minutes as the time his mind switched. Can 10 seconds have that big of an impact over a lifespan?
100% yes.
One tiny moment can fully change out personality/behaviour. It doesnt have to change 100% ALL of the time.
But every now and then is can switch into that "state" and for some its 24/7.
It can make or break you. ...or drive you insane.
and thats Exactly why parenting classes should be mandatory. Its the most important part of someones life.
99% of serial killers are a product of some sort of missfortune in their upbringing/life.
