I used to have this habit as well. I ended up borrowing a ErgoDox Ez from a friend when my normal keyboard broke a few years ago, and bit the bullet and unlearned this habit and a bunch of others, and it was, to me, worth it. I also always typed shift with my left pinkie, no matter what the next character was, even A. I also would ALWAYS look when doing numeric keys, and sometimes other combinations. I ended up with blank keycaps, and broke that habit. You can do it!
