How to get myself threatened?

Thank God for the insightful experience today where I can see on how often I threaten myself by desiring to be somebody else and or to have perfection. 

This morning there was a meeting at 10 am. So I tried to squeeze some time to follow up on the task I promised to do 3 weeks ago with another intern, also to practice for the way to measure which may be helpful for my own intern of which last day is this Friday. 

But somehow I was stuck in a step, a step that was even earlier at the place I am usually stuck. So I was frustrated. 

Then there was a sharing session at 10 am, a very insightful sharing by a great engineer. But somehow I became stress, probably because I come to a realization of two things. One is the gap with him is very big - of course it is big - so perhaps it is more that it is difficult for me to know and accept where I am. Secondly is that I realized that there are a lot of things to do for my own work while I keep trying to take extra job and help others in office beyond my scope of area. 

So my mood changed, I didn't talk much during lunch. And after the lunch, I was still moody. To make things worse, a colleague asked something that I borrow, and I realized that I haven't done another thing that is long overdue. I had to learn the humility to say that I haven't done what I wanted and return her the materials first. 

By that time, I tried to encourage myself that I can stand that feeling as previously shown. I felt bad when I need to quickly learn something again which I have postponed. Then afterwards attend another meeting. There were the time where God reminded me again, that I may be slow in some thing, but I can be average or faster than average for another thing. 

Afterwards, I was still stressed as there are many things to do. Thank God that I can decide and try again the things I couldn't do this morning. Surprisingly, I managed to find my mistake myself, something that is very simple. And afterwards, I managed to complete that task. 

I am happy with it. But at the same time, it realizes how heavy I put my worth on the achievements of my work. So I need to learn to let go and focus on giving our part, solving the problems we have as my calling instead of something that I use to define myself.
