Must Concentrate

I just cannot concentrate. This is don't know how many million time I've said in this blog that I am lost and this and that.

The Weihong 4months ago was someone who concentrate and helpful to all and will do the task allocated to him and even going the extra mile to perfect things. 4 months later, he is lost and cannot seemed to be able to concentrate and even the road ahead of him seems to have bend and still finding his way out of Silent Hill. What's wrong with me? Is it because this place is no longer worth working for? Am i bored of this place? Or its just me that who have become tired? Are these just excuses? I really have no idea. Just hope I can find myself back because its time and I've lost my principles and practice. Very vexed.
