"It will not work anyways, so i will not do It", "It is too hard, i have no chance", "i don't see any meaning in my life anymore, so i don't care if it will harm me", "people are all bad and they will never change, i don't need them", "i prefer dogs than humans", "i am a lost case, i will never be in a better situation", etc...
But...
"Faith is the solid reality of what we hope for, the proof of what we can't see."
Hebrews 11:1
