I love making new blocks!! Meaning ... different blocks. That is why I enjoyed the boomerang groups that I belonged to so much (not to mention the great variety of scraps I was able to accumulate).
Making 1 block then moving on to a completely different block is my favorite thing. Which is why I will be starting a Dear Jane very soon. You might want to consider this if variety is your spice of life.
That said, I DO have a large project going that is a repeat of two different blocks - 110 of one and 111 of another. I've completed all of one block and am perhaps 20% done with the other block. At times I need the monotony of "keep making the same block" and I make a ton of them. Then I get bored and move on to something else.
