Honestly, the last time I had to fill out one fo these I wrote:
"I rule, and deserve a raise and a promotion and then a raise again."
When I handed it in my boss understandably had questions and concerns. I just told him, there is no way to objectively fill that out without a bunch of hackneyed and cliché BS that is essentially just blowing smoke up my own ass along with yours. Waste of time.
If you want to evaluate me, sit down and talk to me and make up your own mind or look at my work and see for yourself.
I hate self-appraisals.
What? You're too lazy to even evaluate me yourself? Weak.
