A mistake I made multiple times was not listening to advice people gave me; whether or not they were huge richardheads, or whether or not I believed them. I'm not saying I'm not a richardhead, or I'm right, I'm just saying that if you feel like you've made the mistakes I've made, keep in mind that you always learn from a mistake, if it's really a mistake. :)
