Whoever thinks of you as fixed in your ideas ought to see how quickly you change your mind about some matter of the heart at the beginning of the week. Call it a lightning-quick learning curve, and keep it going through wednesday and thursday, when the more open you are to change, the happier your heart will be in the end. Getting stuck is possibly worse than making a mistake now; keep moving. From friday through the weekend, you're a charismatic animal, and a s*xy one at that. So you're indecisive. Plenty of time for choosing later.
