just a dream

it's weird to think how quickly our wants and desires change. one day you just have to have something, and the next day, it doesn't even cross your mind. what's the meaning of a dream or a plan then if the next day it could be just a passing thought? what do you do if the one thing that you've been wanting for, waiting for for so long turns out to be fake? how do you know when it's the right dream or if it's what you actually want? do you keep fighting for a dream or a desire that could fade away in the blink of an eye? or do you let it pass it by, thinking that you might not think twice about it tomorrow? how do you choose which ones to chase and which ones to leave?
