I don't know if you still call it mental block but every time I try my luck at writing some stuff, I get lost and could not think of anything good to say.
I am that kind of person who does not write or say things randomly per se. Whatever I say or do, I always carefully plan that out in my mind, although sometimes I guess it's also good be as spontaneous as much as possible.
As you can see, I haven't updated this blog for a long time. It's not because I was too busy - although partly I was. It was more of "what do I say" dilemma.
