My dad can fix anything

How many times have you heard that phrase?? My dad can fix anything!!??
Maybe it was something everyone was raised to say? or did people start saying it cause when you had no money you had no choice but to fix everything by yourself?
Though how true is this really? does just having the belief that everything can be fixed or any problem can be solved, makes the impossible solution become possible?
Our beliefs often have lots of power and there are many stories where people just follow their beliefs and dreams come true.
So maybe i should just change my beliefs and regardless of time and how it will be done, it will get done, someday.
Anything can be fixed.
