Many underestimate my importance, yet without me this world couldn't possibly survive. I come naturally for some, but others both try and struggle to obtain me. I can change your future for the better, but that doesn't mean it will be easier. What am I?
Not only am I powerful enough to hurt like no other, I also have the power to heal like no other, but just like everything else, I can break. Life would be impossible without me, but it's already near impossible to find me. What am I?
