The day of the small feeling

Ah yes, these moments come.
You know, for those people who loves giving themselves away, there's always a point when they feel empty.
Somehow, it disturbs me, because I'm having similar feelings right now.
I'm a bit scared that my client will not want my work.
I'm a bit scared that my agency may let go of me since I have been "consistently good" but I haven't "got anything new to bring to the table."
At this point I do feel stuck, although I am SO thankful to the clients who keeps staying with me no matter what. I love working with them and they always appreciate my work despite the growing demands of this business.
I mustn't forget that being a Phlegmatic, I am constantly consistent. At work or whatever.
Everything is predictable, although I always do it with my best--if I'm not preoccupied by another emotion, that is.
And now, I feel a bit small, because my works are less exciting.
