Swift programming

2017/11/12. Swift programming 

I started learning Swift programming. 
I feel small fun, there are many difficult things, but I want to keep trying to make my own app programs!

One person said, “Things are done, not by wishing, but by working.” 
I want to work for programming master in my private time.
And the environment of programming is already in front of me,
I only try to master Swift progrmming as same as English.
I have been learning English for 3 years, this terms makes me feeling suddenly, but No…
Mastering something new needs long time, and the skill is not lost in short time.

Slow learning makes the skill longer. I learned this by English learning.

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
