I'm hardly the one I've known to be around the longest, but it isn't something you can exactly depend on, either. The way I see it, you can have an outline of what the future may include, but you also have to be ready for none of that to ultimately be feasible.

Even if you do stay indefinitely, there's no promise that other conditions won't change.

[ it's not really happy advice, but you can't be in this kind of situation this long without becoming jaded. and some people are just biologically predisposed to be very jaded. ]
