Undelivered cards... ...

I have bought some cards... planned to write something to a person during special occasions... however, some of the cards still lay on my desk as I do not know what to write… even I have some words in my mind, end up the cards remain blank… hahaha… thinking too much is the root of cause, I understand that… yet, how to overcome it? It’s a negative cycle for me, as I still have no solution and keep questioning myself… sigh…
