I do have one plan: French language lessons on a Saturday morning. DH gives his full support... he agrees I need the mental stimulation. I'm the kind of person who also does well in groups... I can really focus when in a formal learning situation.
Do it! I do French every Saturday morning and it's the highlight of my week. Same for most of my classmates - they're such a diverse bunch but for all of us Saturday morning is just a total break in our routine.

I'm already thinking of a trip to Japan after our French sojourn and it's partly because I would have a chance to do Japanese lessons lol.

As for laziness, I don't think that I'm lazy. I'm just very cerebral - I really have to push myself to do housework because it provides me with zero mental stimulus. On the other hand I never ever had the problems with researching essays that my classmates had - research is a pleasure to me and even though I'm no longer in any formal education I still find myself reading every book I can lay my hands on about any topic that catches my interest.
