Yesterday found a bug in my delivered product. Although not all my faults but still struggling because if I can be more careful it may not occur. And if it happened suddenly I kind of nervous and keep consulting my colleagues about how to fix it, which if I take time, I could find out myself. So didn’t feel quite easy last night, even couldn’t fall deep sleep.

Today kind of remove all the error and found it not a big deal from my colleagues.

Can’t still control myself and remain calm when emergency happened. Can’t still full concentrate on what I’m doing.
