Setting goals is the easy part. Keeping them is another. I totally can relate. Anyway, you should join one of the Scrapbook page challenges that is listed on this forum to help motivate you. That is what I had to do to get my self in gear.
As far as page planning goes, I usually go through magazines and get ideas for my pages. Even looking online for ideas is the way to go. I love books like Page Maps. They have wonderful ideas for planning your layouts.
Good luck with your scrapping.
