Always be strong.
いつも強くいよう。
Especially in a business environment, not everyone is supportive—even when you work really hard. Even your boss doesn’t always care about you.
That happened to me a long time ago. My boss ignored me entirely, and it really hurt me. At that time I was not mentally strong enough, and I quit the job. That was a bad decision, because I completely missed the opportunity to be much stronger during tough times.
Everything happening to you is an opportunity. Stay strong, and never give up.
