Okay, this is just my humble opinion so take it for what it's worth. It sounds to me like you haven't yet come across the pattern that 'touches your soul' - the pattern that you lay awake at night thinking about colors and fabrics for - the pattern that you want to make no matter what it takes. I have found, personally, that if I don't absolutely feel in love with the pattern before I start, I lose interest and have to force myself to finish, and it begins to feel like a punishment. Instead of looking at patterns in terms of how to put them together, try looking at patterns as to how they make you feel. Again, just my humble opinion.
