UFO, why and why not?

OK, now everything has been moved from around the house in to one big room. That is a very good thing, but it also shows all of my UFOs...
I do envy those that don't have UFOs. They must have either discipline or a lot of work in progress.

I have been wondering about these UFOs, why do I have them and why shouldn't I have them??
In some cases it is because I made a mistake somewhere and I don't know how to fix it. It can also be that I can't find the right fabric. Those two reasons of having UFOs are sort of OK! LoL
Then there are all those blocks around. Some of the log cabin blocks in the picture are from a swap. I couldn't decide how I wanted the layout, so they became a UFO...
Other blocks I wanted to make in to pillows for the daybed. No idea why I left them! I do want lots of pillows and I have 3 blank ones so no excuse there!

There is one pile of blocks from the Orange mystery a while back. I didn't like they way my blocks looked, so they are waiting for the quilt fairy to inspire me.
I have one last category of UFOs. They are where I think a project is just too ugly to finish! Have no idea what I was thinking when I use some fabrics together. LoL

That was about the WHY, now to the WHY NOT.
I am embarrassed that they are that many, but I don't mind having some UFOs. So what if I have some things I didn't finish! I am my own boss and if I don't like the way something is going I can just put it away. If I see something exciting I want to try, I will do it and then what I am doing can wait. I am fine with the fact I have some blocks I didn't used. If I need a present in a day, I can make a table-runner fast.
Or am I just making excuses in order to calm my bad feelings about having UFO???
But I do promise myself that I will try to have some of them done by Christmas! LoL
