I have heard that willpower is finite and every person starts their day with a limited capacity.
On the other hand there are people like gym goers or sportspersons saying that they can muster up more will power if they have the right mentality at the right time.
I don’t know which one is right, but is it possible to increase one’s capacity for will power ? If so what kind of exercises or training methods do they have to use ?
That claim is absolutely bizarre and you should probably stop listening to anything coming from whoever told you that.
