Stitching blogger question

Do you have rules in the way you stitch? (i.e., Do you start in the middle? Do you determine which blocks to stitch first? Do you always start from the top or the bottom? Do you have special paths to prevent wasting thread?)
After a few decades of stitching this is what works best for me. I start up at the left hand corner and work down. I tried in the middle, but working up is frustrating. My friend Nancy said she starts in the right corner and works over to the left. Not necessarily a leftie trait, my dear.
