"Shut up!"

I think.

"If it has to be done, it has to be done". It is an engineer.

No matter what the technology, start from anywhere, buy tons of materials (at my own expense), read the Web, bow down to everyone (even the jerks), and then start from scratch again and again -- that's what being an engineer is all about.

It is a world in which there is no 'end', in which I keep moving forward as far as possible in a multi-dimensional space consisting of time, society, and technology.

I have done so until now, and I believe I will continue to do so in the future.

Incidentally, my company is now starting the system called the "Digital Human Resources Certification System".

I'm going to observe my co-workers carefully.
