Ok, here's my problem: I am utterly failing at Corinda's step one. I seem not to be able to write a single letter or digit. Am trying to use the boon, because I keep my nails really short and other types feel really uncomfortable, but cannot find a correct position on the finger.
I know that the solution is "keep trying until you are able to", but I'm getting really annoyed at my inability and, since this is the "Support and Tips" forum, I am looking for a bit of support

Also tips, if you happen to have them.
If you want to know the problem: there are things that are barely readable and others that I am just not able to write. Number 8 is making me crazy.
Also, does anybody have any pictures of how he/she actually use the thing? I. e., the actual position on the hand?
