Ahimel, I didn't read all of the responses to the posted question you linked to, but without derailing too far, I'd offer you the advice that the one reason you should never feel guilty about receiving a gift is that the person who gave it chose
to do so. Let the good stuff happen!
I think the biggest challenge I have with all of this is that I feel like it's really, really easy to ruin all your progress without lifting a finger. I feel sort of like this poster
does on the site carenkh linked to -- it's pretty exhausting sometimes to have to maintain that level of high-mindedness.
OTOH, there are lots of times when I start to get really excited about something (as Lil Chris mentioned) and a voice in my mind says "Don't get worked up, you need to be a grownup here and buckle down and take responsibility and not get your hopes up over something silly and grump grump grouch grump." If silencing that
guy is key to making things work, then I'll gladly make the effort.
