I often find that there's not any satisfactory way to calibrate my expectations for things like this anyway. I was once emailed by someone who wanted to buy a domain name from me. He refused to give an offer, asking me to provide a price. I found it impossible to gauge what it was actually worth to me, or what I thought it would be worth to him, so I said I wouldn't sell it unless he made an offer. I never heard from him again.

So, sure. My future self can be convinced of a new minimum, for all I care. I apparently hold my ideas about this very lightly anyway. I'm not even sure he'd (I'd) be "wrong," even if I currently think of it as a lie.
