Janie - wow, glad to have had a good effect!! Exactly - I have the words of my favourite teacher in my head: Seize every opportunity
Willow, Stacey reminded me of something else. I've done some of this course on-campus (pre-child) and the rest distance. Distance wasn't so bad when DS was younger, but increasingly not possible nowadays. I'm actually on campus now, with DS in care in the next building, because at home I realise I get nothing done except stress that I'm not studying! DS takes up my headspace (he's a very welcome tenant, there, mind you ) when home, so I decided to spend two days a week at uni. Unfortunately, it would appear that with the whirlwind of home left behind, I use this campus time to gather my thoughts and have 'down time', instead of actually working hard on uni work. Soooooooooooo...I've enrolled into on-campus mode for next year, to see if the structure of that will help my brain-organisation. It's only one unit per semester I'm doing, so I won't be in class all day even the days I'm in, but that's ok because the rest of the time I can go to a study space far more 'in the zone' after a lab or lecture, and THEN go home and try to separate the two headspaces as much as I can. It's harder to do that with study than work, because, invariably, what you are learning and thinking about for assignments is in your head, not on your desk in an office. I find this to be my biggest study challenge by far, in all my years at uni (far more than I care to admit to right now!!). Just another thought to echo Stacey's comments about that.
You WILL have the days of "why am I doing this?", so you need other people around you who can pick you up by the shoulders and repeat your goals back to you when you seem to have forgotten the bigger picture. My DP doesn't have an academic background and just doesn't know how to be my cheer squad (thinks 'reverse psychology' like "I guess you just don't want to pass" will work ), it's just not something his family valued before meeting me. I DO have my mum who can be good sometimes, as well as my other friends who know what I want to do with this thing ...not to mention the university counselling service when it all seems to be falling apart at the seams (like now).
And there's always this thread, when you are really struggling for internal motivation!!

ETA:
If it all seems like it might be a bit much right now, keep it in mind for 12 mths or 2 years and look into it again.
Yes! Thanks, Jennifer - great advice
