Business trip impressions

I have been on a business trip for more than a month and have been depressed for more than a month. I don't know why I have always been dissatisfied. I always hate my manager. Why did I say I may have to go on a business trip? But in the end, I spent more than half of my time on a business trip? I don't know. Shouldn't people be built on mutual trust? Alas, depressed.

What's more, I don't know why developers need this business trip. no, it should not be said that it is a requirement. We started development without a requirement. why is it like this? I don't understand. Why are there so many problems with a system that has been running for two or three years? More and more difficult to operate, more and more complicated. Do not understand.

Besides, why do people who have been out for a few years still write this?Program: A table is a class. A class has dozens of attributes and only dozens of attributes. I am dizzy.CodeIt becomes more and more difficult to maintain. Later, I did not maintain it, but I wrote it myself.

Finally, why does a system have no logical abstraction? Why are we operating SQL-level things? Why is it so slow to query databases that only have dozens of GB? Why are there so many? Why?

Oh, And, why am I supposed to work with you till the early morning?
