In my mind the meaning of life is just to have fun and live it to the fullest, and for why do we live, well if your asking like what created us or how we came to be that I don't know but if your asking why to keep going then I'd say just for the shower thrill of not knowing what will happen tomorrow, could be a normal day, could be a bad one, and heck you could end up getting $1mil, you just never know
