Learning to let it go

Well I guess this week this applies to more then just my knitting...lets just stick with the knitting. I have now started and ripped out a scarf from the Victorian Knitting Today for my mother 3 times. Before this I had never frogged a project just a swatch. But I'm learning more and more to let it go. However long I've spent on those projects it doesn't matter because if I'm not happy with how they are now, chances are that I won't be happy with them 100 hours and 400yards of yarn latter either. So today I will be casting on the diamond pattern wide border scarf AGAIN. I've now switch needles 3 times and yarn twice.....maybe the fourth time will do the trick? Well at least I'm still optimistic, kinda.
