I don't want to hear complaints. 
There's no time to listen to them.
I don't know if you're frustrated with people  
or with you company,but if you change yourself,then others will change as well.
That's what I believe.
If you have time to complain,you should use that time for self-analysis.
Once you do that, your complaints will fade away and you'll remember the joy of being provided a job.

愚痴はいらない。そんな事を聞く暇はない。
人に不満があるのか、会社に不安があるのか知らないが、自分が変われば、相手が変わる。僕は、そう思う。
愚痴る暇があったら、自己分析するといいね。
そうすれば、愚痴は消え、お仕事を頂ける喜びを思い出せると思う。
