New system (my work)

The new system which I am in charge of starts on December. I had planning for start it, and too well-preparing.
I have worked on the project when I thought it was OK, without hesitating. I always do the best to hope best result. I think my thinking seems to be working so far.

But recently I lost my thinking.

I think, maybe I sometimes need to remain on the sidelines while maintain a reasonable level.

But .... I can't very enjoy this work.

Oh well..
