trying

I've tried sooooo hard but it's never enough
it came to a point that I've thought to myself
why keep on trying if everything is gonna end up not working out anyway?
people say
if you're thinking of giving up, think about the reason why you hold on in the first place?
but
what about if the thing holding me back from giving up is not there anymore? gone. poof just like that.
then what?
why keep on working on something that's meant to be a dead end?
