No, you're not speaking just for yourself, I feel the same way.
Apart from seamless knitting, as already mentioned by Jan, I don't have any avoidance strategies (unless you count the heretical suggestion of 'Don't knit.':noway:).
The way I cope with seaming is to break it down into smaller chunks. So, I'll tell myself something like "I'll do this sleeve seam" or "I'll do 15 minutes". If I'm in the mood to carry on and do more after that I consider it a bonus, but if I'm not then I don't feel guilty as I've met my target.
