The Last Thing

In his blog, Scott Dinsmore encouraged his readers to share the last thing they want to tell strangers.
Well, the last thing I want to share with 4300 people I don't know is the fact that I really can, but hiding it.
Does it make sense?
No. OK, an example:
I am able to complete tasks I set out, but I do not communicate success.
I guess Csíkszentmihályi is right about Hungarians and about things that give them flow.
