Thanks for answering!

I'm really trying to learn from my mistakes. Like realizing that any negative feeling I have at one moment won't last forever, so I can't take it out on my clients. I'm also trying to identify my stressors, so I can deal with them before it affects my performance.

I think the main problem is that I expect 100% from myself 100% of the time. Being good 80%, or even 99% of the time isn't enough, so I will minimize what I have done well and dwell on what I haven't achieved. Plus, I have a hard time with rejection. I want to be liked by everyone.

The fact is, I'm only staying at this job for the flexibility and the salary. I lost my passion a long time ago, and most of my colleagues know I hate my job, but I stay anyway.

I'm going to do what you suggested-- make a list of my strengths. Hopefully it will re-ignite my confidence and trust in myself!
