I'm fairly new to knitting too. When I got sick of scarfs I did a baby blanket with a checkerd board pattern. It was a small baby blanket and I felt like it was NEVER ending. Then about 9 months ago I decided to do a "thick and fast" afghan.... thick, yes... fast... well I guess it was faster than it would have been if it wasn't so thick and didn't use big needles. But, again it felt like it would NEVER end. I finally just said I'M DONE! and just stopped and finished it. Now it's a little smaller than I wanted but it's perfect for a lap blanket.
My advice is to try something that can give some immediate gratification. I usually enjoy the process of activities not only the end product. But afghans got boring too fast for me. I have a new appreciation for scarfs now and I'm also trying mittens. It's a learning process but at least I can see the end much faster.
Good luck on whatever project you decide to do!
