Usually saying that someone is thirsty has a negative meaning, but I don't see it like that, not unless you are begging to have a tall glass of chocolate milk. I've been called thirsty many a times, but I don't mind, because I am!
I'm thirsty for love, lust, passion, money, beauty, knowledge, wanderlust, everything, you name it. Even thirsty for blood at times. And I don't hide any of it.
I want things and experiences and people, and I am passionate. I have no reason to hide what I want. You can't get what you want if you don't first ask for it. Daddy, can I have a car? No, oh, alright then, at least I tried...
I consider not being thirsty a lot worse than being thirsty. Maybe you are not thirsty because you have everything you need and want in life, and all your dreams are fulfilled, but I highly doubt that. I see people without any sort of thirst or hunger, going about their life in an orderly fashion, lacking passion and living a lukewarm life. It's fine if you truly are happy like that, but it's not the life for me.
I always want more and better and bigger, I have dreams and goals and I don't settle for anything. I work my cute little ass off while trying to get everything I want in life. If I don't get it all, I'll die trying, but I die knowing I tried my best.
What are you thirsty for?
Ps. I'm also thirsty because I'm always dehydrated for not drinking enough water.
