Digging this! There is something very hooman happening here.
There is much that can be deduced from a person's hand writing alone - perhaps you're a leftie? I know that certain ways of writing letters can point at different personality traits (though i'm not able to do the analyses myself)...
But other than that, yes, paper is commitment - you trust you mind and hand and see your thoughts through. Just typing all this I have deleted my lines several times - my true impulsive thoughts may never be known.
Much more to say (since i'm not limited by the size of the paper), but I'll leave it here.
Following for more.
