I've only just signed-up and was about to post a 'hi' when I saw yours. Equally, well done on your changes so far.
I think the important things are:
1. Keep it fun: can you make your changes into games? - this has fascinated me in some
writing I've been doing recently that might help you as researching it has helped me?
2. Don't beat yourself up - you've done amazingly: a lot more than a lot of people can ever hope for
3. With how well you've done, have you reset your vision and goals? Why not aim for a marathon or a novel to keep to your commitments?
Look forward to seeing you on the forums
Take care
